[brmarcum] takes us back to analog building block basics with his Frequency Modulation and Demodulation tutorial. Frequency Modulation (FM) sounds simple at first, but understanding the ...

Demodulation of frequency modulation (FM) signals can be done in many ways. There are FM discriminators, ratio detectors, quadrature detectors, phase lock loop designs, and even methods of getting ...

This is known as Amplitude Modulation (AM). Figure 3-2. An amplitude modulated signal. The demodulation process for AM where the radio frequency signal is converted into an audio frequency signal is ...
