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 ...

The DB3000 FM Modulation Analyzer is a fully DSP-based digital FM demodulator and modulation analyzer. The RF (IF) and MPX signal is digitized as soon as it enters the device, and all signal ...

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, ...

The TBA120 Series ICs provide a high-gain limiting IF amplifier and a quadrature coincidence detector in one package. These ICs are primarily intended for extraction of TV intercarrier sound, which ...
