Pulse-position modulation — is a form of signal modulation in which M message bits are encoded by transmitting asingle pulse in one of 2^M possible time shifts. This is repeated every T seconds, such thatthe transmitted bit rate is M/T bits per second. It is primarily… … Wikipedia
Pulse-code modulation — PCM redirects here. For other uses, see PCM (disambiguation). Pulse code modulation (PCM) is a method used to digitally represent sampled analog signals. It is the standard form for digital audio in computers and various Blu ray, Compact Disc and … Wikipedia

Pulse — The rhythmic dilation of an artery resulting from beating of the heart. It is often measured by feeling the arteries of the wrist. * * * Rhythmic dilation of an artery, produced by the increased volume of blood thrown into the vessel by the… … Medical dictionary
pulse — I. noun Etymology: Middle English puls, probably from Anglo French puuiz gruel, from Latin pult , puls, probably from Greek poltos Date: 13th century the edible seeds of various crops (as peas, beans, or lentils) of the legume family; also a… … New Collegiate Dictionary
pulse modulation — noun any of a number of techniques whereby a series of information carrying quantities occurring at discrete instances of time is encoded into a corresponding series of electromagnetic carrier pulses See Also: pulse modulator … Wiktionary
pulse modulation — A number of methods of converting CW (carrier wave) signals into digital pulses to reduce the bandwidth required, eliminate errors, and, where possible, improve the signal to noise ratio … Aviation dictionary
Delta-sigma modulation — Delta sigma (ΔΣ; or sigma delta, ΣΔ) modulation is a method for encoding high resolution or analog signals into lower resolution digital signals. The conversion is done using error feedback, where the difference between the two signals is… … Wikipedia
Delta modulation — Principle of the delta PWM. The output signal (blue) is compared with the limits (green). These limits correspond to the reference signal (red), offset by a given value. Every time the output signal reaches one of the limits, the PWM signal… … Wikipedia
Quadrature amplitude modulation — (QAM) (Pronounced IPA|kwa:m) is a modulation scheme which conveys data by changing ( modulating ) the amplitude of two carrier waves. These two waves, usually sinusoids, are out of phase with each other by 90° and are thus called quadrature… … Wikipedia
Modified Frequency Modulation — This article is about Modified Frequency Modulation. For other uses of MFM, see the MFM (disambiguation). Modified Frequency Modulation, commonly MFM, is a line coding scheme used to encode the actual data bits on most floppy disk formats,… … Wikipedia
