What is Pulse Code Modulation and Demodulation? Pulse code modulation is a method that is used to convert ananalog signal into a digital signalso that a modified analog signal can be transmitted through the digital communication network. PCM is in binary form, so there will be only two possibl...

where ωcdenotes the carrier frequency. Note thata(t)represents an on-off rectangular amplitude modulation of the carrier frequency. After demodulation, the complex envelope ofx(t)is the real-valued rectangular pulsea(t)of duration τ seconds. ...
Method for combined filtering and differential pulse-code modulation/demodulation of signals FIELD: information technology. SUBSTANCE: error signal is generated as a result of averaging on each time interval the difference between an input signal and an extrapolated estimate of the information signal; er...
H Wei,I Andonovic,M Tur 摘要: A code acquisition technique based on active optical correlation detection is introduced for coherent optical pulse code-division multiple-access (CDMA) systems implemented through coherent correlation demodulation. Passive matched filter acquisition, commonplace in most ...
pulse code modulate the FM carrier signal used in standard video recording. The recorded signal is demodulated on playback to reproduce successive digital words that are converted into discrete analog values which are low pass filtered to reproduce the original audio signal. The reproduced digital ...
