The original signal and the phase-shifted signal are then passed into a multiplier or mixer. The mixer output is dependent upon the phase difference between the two signals, i.e. it acts as a phase ...

Frequency modulation can be changed to phase modulation by simply adding a CR network to the modulating signal that integrates the modulating signal. As such, the information regarding sidebands, ...

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users ...

National Institute of Standards and Technology radio station WWVB(AM), near Fort Collins, Colo., is conducting another phase-modulated broadcast test beginning at 11 a.m. Pacific on Tuesday, Sept. 4..
