pulse amplitude modulation
11Pulse-density modulation — Pulse density modulation, or PDM, is a form of modulation used to represent an analog signal in the digital domain. In a PDM signal, specific amplitude values are not encoded into pulses as they would be in PCM. Instead it is the relative density …
12Pulse Code Modulation — Modulation d impulsion codée Pour les articles homonymes, voir PCM. La modulation d impulsion codée ou MIC, (en anglais Pulse Code Modulation, généralement abrégé en PCM) est une représentation numérique non compressée d un signal analogique via… …
13pulse-time modulation — noun modulation of the time between successive pulses • Hypernyms: ↑pulse modulation * * * /puls tuym /, Electronics. radio transmission in which the carrier is modulated to produce a series of pulses timed to transmit the amplitude and pitch of… …
14Pulse Code Modulation — Die Puls Code Modulation ist ein Verfahren, um ein analoges Signal in ein digitales Signal bzw. Binärcode umzusetzen. Es wird für Audio und Video Signale verwendet. Die Umsetzung erfolgt in folgenden Schritten: Abtastung des analogen Signals… …
15pulse-code modulation — /puls kohd /, Telecommunications. a form of modulation that transforms a wave form, as an audio signal, into a binary signal in which information is conveyed by a coded order of pulses for transmission, storage on a disk, or processing by a… …
16Quadrature 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… …
17pulse-frequency modulation — A signal is translated into a succession of constant amplitude pulses transmitted at a frequency proportional to the amplitude of the original signal. See pulse modulation …
18pulse time modulation — noun : modulation of the time intervals between successive pulses of constant duration and amplitude in accordance with a signal; specifically : a system of multiplex high frequency transmission using this method of modulation …
