This demo video shows using a Rigol DG4000 Series Arbitrary Waveform Generator and a DSA1000 series of Spectrum Analyzer to create and demodulate an FM audio transmission. This demo video shows using ...

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, ...

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 ...

The completed composite demodulator with wall wart. At the end of the pipe in every FM station operating in stereo — which probably is 99.5% of the over 7,000 FM outlets operating here in the United ...

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 to ...

High resolution encoders are expensive, but alternatives exist. You can develop a high-resolution system using a sinusoidal encoder or resolver. Last month, we covered some of the basics of using ...
