The passage of phase-shift keyed signals through the band-pass filters at operational amplifiers

摘要

At present the phase-shift keyed (PSK) signal is widely used in communication, radar systems, navigation. To obtain the reliable recommendations for developing an important class of the system where the information carrier is the fine phase structure of the radio signal, it is necessary to use strict computing techniques. At digital signal processing in such systems it is extremely desirable to determine precisely the informative characteristics of the amplitude and phase of the radio signal agreeing with their physical correspondences. Transients in SSP with identical band-pass filters greatly distort the form of the signal at the phase manipulation. The law of phase shift may present a pseudorandom sequence with the further correlation processing of the signal (modern systems with the code division CDMA).
