Spectrum continuation analysis — (SCA) is a generalization of the concept of Fourier series to non periodic functions of which only a fragment has been sampled in the time domain.Recall that a Fourier series is only suitable to the analysis of periodic (or finite domain)… … Wikipedia
Phase noise — is the frequency domain representation of rapid, short term, random fluctuations in the phase of a wave, caused by time domain instabilities ( jitter ). Generally speaking radio frequency engineers speak of the phase noise of an oscillator,… … Wikipedia
Phase-locked loop — PLL redirects here. For other uses, see PLL (disambiguation). A phase locked loop or phase lock loop (PLL) is a control system that generates an output signal whose phase is related to the phase of an input reference signal. It is an electronic… … Wikipedia
Phase Shift Keying — Die rote Sinusschwingung ist gegenüber der blauen Sinusschwingung um ein Viertel der Periodendauer verzögert. Im komplexen zweiseitigen Frequenzspektrum zeigt sich das als eine 90° Drehung der beiden Spektrallinien, die den Träger darstellen. Die … Deutsch Wikipedia
