	Digital Signal 1 - Wikipedia, the free encyclopedia
		Digital signal 1 (DS1, also known as a T1) is a T-carrier signaling scheme devised by Bell Labs.
		Signaling frame alignment channel is carried in even-numbered frames inside the super frame and is used for signaling frame alignment.
		Signaling frames are identified by the framing signal's transition from 1 to 0 and from 0 to 1; thereby frames six and twelve carry signaling information.

		Digital signal processing (DSP) is the study of signals in a digital representation and the processing methods of these signals.
		A digital signal is often a numerical representation of a continuous signal.
		Typical applications of digital signal processing are, for example, speech compression and transmission in (digital) mobile phones, equalisation of sound in Hifi-equipment, weather forecasting and economic forecasting, analysis and control of industrial processes, computer-generated animations in movies and image manipulation.

		The target of the signal processing is often another analog output signal which requires a digital to analog converter for translation.
		The continuous signal is usually sampled at regular intervals by an Analog to digital converter and the value of the continuous signal in that interval is represented by a discrete value.
		Signals are converted from time or spatial domain to the frequency domain usually through the Fourier transform.

	MEM:Digital Signal Processors (Fall '99)
		Digital algorithms that work on the sampled signals should execute quickly and meet real-time constraints before converting these digital signals back into their analog form.
		Signals in the real world exist in analog form, and they are always a composite signal with known and unknown elements.
		Signal processing is done on fractional numbers, and, while performing calculations, there are intermediate values that must be corrected with saturation logic to avoid overflow and underflow.

	Digital signal processor (Site not responding. Last check: 2007-10-17)
		A digital signal processor (DSP) is a specialized microprocessor designed specifically for digital signal processing, generally in real-time.
		Most DSPs are fixed-point, because in real world signal processing, extra precision is often not required, and there is a large speed benefit; however, floating point DSPs are common for scientific and other applications where precision is required.
		Present-day general-purpose microprocessors also have ideas and influences from digital signal processors, such as the MMX extensions in the Intel IA-32 architecture.

	Improving Design Efficiency with Digital Signal Controllers - 1/1/2001 - ECN - CA203482 (Site not responding. Last check: 2007-10-17)
		Designers wishing to add digital signal processing to embedded control applications are faced with the daunting prospect of developing DSP theoretical expertise and then learning an unfamiliar architecture and tool set, a time-consuming process that directly opposes time-to-market goals.
		Digital signal controllers provide a single chip solution that can eliminate additional components that would be required for a similar design today, resulting in reduced board space and system costs.
		The 16-bit dsPIC digital controller uses a new breed of device which is intended to be a natural bridge for microcontroller users who require increased performance or plan to augment their applications with DSP capability.

	DS1 - Digital Signal Level 1 (Site not responding. Last check: 2007-10-17)
		The signal to noise ratio was inadequate because the signals were converted back and forth between digital and analog signals causing quantization noise to accumulate.
		The signaling bit in the 6th frame is known as the A-Bit and the signaling bit in the 12th frame is know as the B-Bit.
		The sixth and twelth frames are represented by a 0 to 1 transition and a 1 to 0 transition in the signaling framing bits, respectively.

	Digital cameras vs. film, part 1
		With a digital camera, the steps are (1) digital capture, involving filtered sensors, (2) Bayer interpolation (except for Foveon), which doesn't affect color quality, (3) Image editing (no generation loss either, but lots of potential gains), and (4) Printing using pigments or dyes.
		With film the steps are (1) Exposure, using layered film, where dye-couplers determine the sensitivity of the layers, and (2) development, where the dye couplers determine the color (light absorption) of each layer.
		The MTF of CCD digital sensors is affected by diffusion or "blooming" between pixels.

		A digital source, or terminal, is the equipment that generates digital signals for transmission through the digital network.
		What happens is a single T1 signal is generated using channels a and b and goes to the CO. The CO splits this into two T1 trunks one carrying channel a and the other carrying channel b.
		The output of the CSU is the DSX-1 signal.

		SINAD of 10 dB with bandwidth of 3.2 (1.6 CW) kHz and the input signal tuned 400 Hz from the dial frequency 0.005 MHz..................
		The receiver frequency scheme uses only one mix: a single synthesizer local oscillator tuned to the desired signal frequency converts a signal directly to baseband, or the zero-frequency "IF signal." Baseband signal waveforms are filtered and demodulated under the control of digital signal processor (DSP) technologies developed and patented by Rockwell Collins.
