And he adds that tests have shown the signal to be compatible both with current NextGen demodulation devices and analog FM tuners. (Also read: Sinclair Readies ATSC 3.0 Simulcast of Seattle Radio ...

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 ...

FieldFox analyzers now connect to Keysight’s 89600 VSA software for signal demodulation and vector signal analysis.

To demodulate an FM signal, it is necessary to convert the frequency variations into voltage variations. This is slightly more complicated than demodulating AM, but it is still relatively simple to ...

Many if not most of the non-HD stations deliver their composite stereo “package” from the studio via an STL in a signal-ready form for direct plug-in into the FM exciter. Not only is the composite ...

Unsurprisingly, once you have the analog change, you can demodulate it like an AM signal. There is a bit more, of course, but the basic idea is just that simple.

Additional subcarriers are sometimes found in the region of 57kHz–96kHz. Figure 6. FFT at Output of Digital Downconverter Figure 7. FFT of Demodulated FM Signal To keep life simple, we low pass the ...

They occur as simple multiplications.Next month, we'll take the tracking demodulator concept and see how it applies to systems using analog cosinusoids in quadrature to indicate position. Don Morgan ...

WTMJ-AM (620) is going FM. The Scripps-owned news/talk/sports station, which has been on only the AM dial since 1927, is now airing a simulcast signal at 103.3 on the FM dial. "It’s important to ...
