Electronics 53 Times from the hold command are measured from the 1.4 V point of the control waveform. The larger the hold capacitance, the smaller is the droop. To sample, the gate is connected to the drain (or the source), and to hold, the gate is connected to -V. This is not a very convenient way to control the JFET, but it works for a demonstration. mysite.du.edu /~etuttle/electron/elect53.htm   (0 words)

TriPhase/QFG, Sample and Hold,DSC2000 In the second part of the sample, the 0 degrees phase is modulating the Folds input, and the 90 degree phase is modulating the offset input. The sample and hold is fed a triangle LFO waveform. This next sample is of the Sample and Hold being used in conjunction with a Small Stone Phase Shifter clone that I have breadboarded and modified to accept CV. mypeoplepc.com /members/scottnoanh/slsdiy/id21.html   (2140 words)

Sample and Hold Macro - Winter 1997 The purpose of a sample and hold macro is to quickly store the amplitude of a sampled input waveform, and then to maintain that amplitude until the next sampling pulse. Tin is the period of the input waveform that is to be sampled. Rout is the output resistance of the sample and hold macro. www.spectrum-soft.com /news/winter97/sample.shtm   (414 words)

Buchla 291 BPF Adaptation The sample and hold is set up in a 'correlation patch', which mimics a Buchla technique - a noise generator is going to a mixer, mixed with the output of the sample and hold and the output of the mixer is feeding the sample and hold signal input. The sample and hold is being triggered by a VCO pulse wave, and that VCO is in turn being modulated by the sample and hold. In the third part of the sample, the bandwidth input again is modulated with the triangle wave LFO, and the resonance is pulsed with a square wave LFO to the point of self resonance only when the bandwidth (slope) is at the narrowest (steepest). mypeoplepc.com /members/scottnoanh/slsdiy/id11.html   (3143 words)

[No title] Sample and hold circuits are used to create repeating or non-repeating cycles of control voltage by sampling a signal fed into the input at a rate set by the sample clock. It is interesting to sample various waveforms and hear the remarkable patterns that emerge as you vary the sample frequency or the frequency of the sampled signal. The 100 uS -V to +V sample pulse is applied to the gate and drain of NFET Q5 which turns it on and passes the pulse through it's drain and to the gate of Q6. www.musicfromouterspace.com /analogsynth/SMPLANDHOLD200607/SMPLANDHOLD200607.php   (0 words)

Metaldog - Sample and Hold - Review at sounduser.com Most of the samples are fairly simple in structure, if not in sound, mostly just consisting of one or two layers of sound (I'd think), which make them more suitable for layering with other sounds. Many of the samples are of the "alien world" variety, metallic, effected, shearing type sounds, deep synth drones and burbling, many have slow attacks or slow repeating motifs. I really did like a lot of the samples in this section though, there are a few ropey ones for sure, but if your looking for an unusual intro or outro to a track, or looking for something different to add into a track you may well find something here. www.sounduser.com /amg/sampleandhold/p3.html   (661 words)

Sample and Hold The job of a Sample and Hold is to memorise the input voltage on command of a clock signal. Here, the hold output actually follows the input signal slavishly, but only when the clock input is below 2V for the clock rising input (or above 2V for the clock falling input). But when the command to hold is given, the 'hold output' is fixed and unchanging. www.oakleysound.com /sample.htm   (698 words)

5.2 Sample and Hold   (Site not responding. Last check: ) The purpose of the sample and hold circuitry is to take a snapshot of the sensor signal and hold the value. An equivalent circuit for the sample and hold is shown in Figure 44. Signal Feedthrough: When the sample and hold is not connected to the signal, the value being held should remain constant. ccrma.stanford.edu /CCRMA/Courses/252/sensors/node22.html   (251 words)

Random sample statistical function analyzer (US3983379) The high speed sampling is initiated upon command from the computer to successively obtain a pair of analog data samples with a predetermined, variable digital delay between each sample pair as determined by command from the computer. The high speed sampling and slow processing and computation steps are repeated successively until a large number of sample pairs at each digital delay value are obtained from which to compute the desired correlation function estimate and/or power spectra estimate. In the preferred embodiment, the pairs of analog data samples are fed directly to a slow multiplexer and a slow analog-to-digital converter for producing digital representations of the analog data. www.delphion.com /details?pn10=US03983379   (812 words)

Sample & Hold - from AMG - Review at sounduser.com Many of the samples are not sequences as you might imagine, but filter swept, gated, delayed, analogue sounds and arpeggio's. Tracks 19 - 21 is back to the synth bass sequences, though bear in mind these are probably as far from the "synth bass" patch on your General Midi keyboard as your going to get, but they're bass and synth generated !. Generally very good indeed, there are a couple that you think, "well how could anyone use that", but if your looking to be different or creative then there is plenty of material in here. www.sounduser.com /amg/sampleandhold/p2.html   (677 words)

Checking Of Preamplifier and Sample and Hold outputs The polarity of the sample and hold output will be opposite, since it is reversed by the instrumentation amplifier. The light signal causes the signal to rise linearly during the integration cycle after the switch S2 is opened (S2 causes both input legs of the instrumentation amplifier to be on the same potential when it's closed). 14: For this trace, the sample and hold pulse is activated. xray1.physics.sunysb.edu /~micros/sidet/node17.html   (289 words)

Electronics 53   (Site not responding. Last check: ) For a hold capacitor of 0.01 μF, this is 0.5 mV typically, 2.5 mV maximum for the LF398. The larger the hold capacitance, the smaller is the droop. To sample, the gate is connected to the drain (or the source), and to hold, the gate is connected to -V. This is not a very convenient way to control the JFET, but it works for a demonstration. www.du.edu /~etuttle/electron/elect53.htm   (1348 words)

SYNTH SECRETS A bunch of samples are held as binary numbers on the CD itself and, on playback, one sample is read and presented to a digital-to-analogue converter (DAC) each 1/44100th of a second. Whereas the samples in Figure 19 were 'taken' at integer times (2, 5, 8, and so on) the equation allows us to calculate the amplitude at any time we like within the span of the given samples. Remember: if the sampling rate is greater than twice the highest-frequency component in the original signal, it is sufficient to represent that signal fully and unambiguously. www.soundonsound.com /sos/sep00/articles/synthsec.htm   (2970 words)

Electronics 25   (Site not responding. Last check: ) The hold step is the change in output voltage when the circut is switched OFF, the result of various capacitive effects. Finally, the dynamic sampling error is the difference between the voltage held and the instantaneous input voltage at the instant of the HOLD command. Hold steps are on the order of mV, aquisition times of μs. www.du.edu /~etuttle/electron/elect25.htm   (1374 words)

Sample and Hold - AMG - Sample CD Review by sounduser.com Sample and Hold is CD no.32 of the AMG producer series this particular volume is produced by metaldog, and promises "extreme analogue samples" in a "multi-processed, distorted and chewed up analogue domain of metaldog, his urban, industrial flavoured 100% analogue library...". Does make tracking down samples a little bit tricky, for example, "Cyber Landscapes" covers 16 tracks and maybe 20 minutes of samples, tracking down the sample your looking for can be a liitle harder than it needs be. There is no mention of the specific equipment used, though I suspect in many cases, as many of the samples are heavily processed, that the sounds presented here bear little resemblance to the original source. www.sounduser.com /amg/sampleandhold/p1.html   (342 words)

CD Baby: VARIOUS ARTISTS: Sample + Hold Unschooled Records' attention to detail in all forms of left-field electronics is clearly evident on Sample + Hold, a compilation meant to brush through a wide array of sounds representing the label as it pushes through 2004 with their roster of musical talent all across the globe. Sample + Hold could easily be considered a cross-section displaying the range of music Unschooled will (eventually) unveil throughout the year. Stepping back to the introductory "Aftur" by Plat, Sample + Hold opens with what could easily be classified as downtempo hip-hop jazz morphed into a relaxed, funky space; full of gently flowing beats, scratches and guitar elements, Plat's distinctive sound veers in all the right directions. cdbaby.com /cd/unschooled2   (607 words)

Sample and Hold :: Blocks (Signal Processing Blockset) The block then holds the output at the acquired input value until the next triggering event occurs. When the acquired input is frame based, the output is frame based; otherwise, the output is sample based. The trigger input must be a sample-based scalar with sample rate equal to the input frame rate at the signal port. www.mathworks.com /access/helpdesk/help/toolbox/dspblks/sampleandhold.html   (397 words)

KVR: Can anyone explain "Sample and Hold"? The first is an LFO as the audio being sampled, and a noise source as the trigger. sample and hold is definately used for random blip bloop pitch contol, especially on modular synths. You cannot sample the frequency at one point, because the frequency is determined by a series of values/amplitudes and not by only one value at a certain point in time. www.kvraudio.com /forum/viewtopic.php?t=143312&postdays=0&postorder=asc&start=15   (2601 words)

Cours en ligne - CMOS Design - Analog Cell Design   (Site not responding. Last check: ) Sample and Hold (S/H) circuits are critical in converting analog signals to digital signals. When sampling, the transmission gate is turned on so that the sampled data DataOut reaches the value of the sinusoidal wave DataIn. The minimum sampling frequency must be equal to or greater than twice the highest frequency component of the original signal. www.lesia.insa-toulouse.fr /~bendhia/Cours/CMOS/sample_and_hold.html   (302 words)

DigiTech® Sound Community :: Guitar Products   (Site not responding. Last check: ) I notice that both the Turbo Flange and the Hyper Phase have a sample and hold setting. Position 7 of the "TYPE" knob on the Turbo Flange and Hyper Phase is a step modulation that emulates the sample and hold function found on analog synthesizers. Since this is only a modulation signal for the effect path, there will be tonal differences between the two pedals in question, based on their individual sound characteristics. www.digitech.com /soundcomm/guitar_view_thread.asp?productid=195&thread_id=1027132500   (167 words)

MOTM 101 Noise/Sample and Hold The benefit of combining these two functions in one module is that the noise generator is hard-wired into the sample and hold section. This is useful if you wan the sample and hold to trigger at the same rate as another module, such as a keyboard trigger or a sequencer. In Hold position, the module samples with each clock cycle, and holds the signal until the next cycle. www.synthtopia.com /synth_review/MOTM101Noise-SampleandHol.html   (856 words)
