	Quadrature Trapezoid VCO: Part 3, Trapezoid Waveform Notes
		The waveform is symmetrical, meaning that the time spent slewing positive, holding positive, slewing negative, and holding negative are all equal, and that the slope of the positive ramp is equal and opposite the slope of the negative ramp.
		The waveform for this article is normalized so that it has a value that ranges from -1.0 to +1.0, a frequency of 1.0 rad/sec, and a phase such that its value crosses 0.0 in the positive direction at x = 0.0.
		Because the two trapezoid waveforms are 90 degrees apart, and the phase of the resulting triangle waveform is halfway between the two trapezoids, the odd harmonics branch away in positive and negative directions from the phase of the fundamental at odd multiples of 45 degrees.

	Advanced Waveform Sequencing and Triggering on Arbitrary Waveform Generators- Developer Zone - National Instruments
		Advanced waveform triggering and sequencing is made possible on a variety of NI modular instruments through its implementation as part of the synchronization and memory core (SMC) architecture.
		In addition, these waveforms can be generated in a sequential manner in what is commonly referred to as âlinking and looping.â With this feature, you can create complex waveform sequences by generating waveforms in a predetermined or dynamic order.
		After the waveform has been looped for the appropriate number of iterations, the last sample of the waveform repeats continuously until the next trigger is received.

	Novel Waveform Techniques
		Although waveform design is always an essential part of the design of active sensors, there has been recent emphasis on new waveform techniques such as matched illumination, adaptive waveform control, and exploitation of waveform diversity capabilities such as spatial or polarization diversity.
		When combined, waveform optimization and sequential hypothesis testing form a closed-loop system that is an example of the more complex closed-loop operation that we hope cognitive radar will eventually become.
		The second is an information-based waveform that depends on the ensemble of channel hypotheses (in this case, the ensemble of target hypotheses), and the third is based on the eigenfunctions of the ensemble's autocorrelation matrix.

	Transmitted television signal waveform equalizing system - Patent 5353069
		For performing the waveform equalization in a sequence of the time domain, the synchronous addition is needed upon every correction of the tap coefficients of the transversal filter, thus increasing the overall time needed for the waveform equalization.
		After the waveform equalization is completed, the CPU 12 turns the selector circuit 7 from the "b" position to the "a" position and also turns the selector circuit 8 from the "c" position to the "d" position for delivering a corrected waveform of the TV signal.
		In particular, a waveform distortion change detector circuit 15 is provided for operating independently of the waveform equalization to examine whether the waveform distortion is varied or not due to a change in the TV signal.

	MITSYN Waveform (sound) File Editor Usage
		The main window view is of channel waveforms (viewing a list of selected channels), and the view is usually set to use fixed scaling (for audio, although not for process simulations), so that the scale will stay constant while paging through a waveform stream file.
		Waveform channel signals are displayed in a time-compressed format, using one of the available forms of decimation such as Range, First, Max, Mean, or RMS.
		In the caption for each waveform segment plot is a field shown as "Decimation: nn, type", where "type" is the decimation type and "nn" is in the decimation ratio (how many samples are represented by each plotted point).

	What is waveform? - a definition from Whatis.com - see also: sine wave (Site not responding. Last check: 2007-10-05)
		A waveform is a representation of how alternating current (AC) varies with time.
		The most familiar AC waveform is the sine wave, which derives its name from the fact that the current or voltage varies with the sine of the elapsed time.
		Household utility current has a sine waveform with a frequency of 60 Hz in most countries including the United States, although in some countries it is 50 Hz.

	Introduction to waveform interpretation
