This application note involves the use of RIGOL’s instruments for FM signal generation and analysis. An arbitrary waveform generator will be used to produce the signal and a spectrum waveform analyzer ...

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, ...

One of the most powerful ways to maximize FM modulation is by peak clipping. Clipping off those peaks or the overshoots that wind up in a system can easily give an FM station 1 dB (20 percent) or more ...

An arbitrary waveform generator (AWG) is a powerful and flexible signal source capable of generating any wave shape within the bandwidth and amplitude range of the generator. Populating an AWG with ...
