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
Amplitude — is the magnitude of change in the oscillating variable, with each oscillation, within an oscillating system. For instance, sound waves are oscillations in atmospheric pressure and their amplitudes are proportional to the change in pressure during … Wikipedia
Phase retrieval — concerns the solution to the phase problem. Given a complex signal F(k), of amplitude |F(k)|, and phase phi(k):::F(k)=|F(k)|e^{i phi(k)},phase retrieval consists in finding the phase that for a measured amplitude satisfies a set of constraints.… … Wikipedia
