[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 ...

There’s another demodulation method that’s not so common ... usually at the zero-crossing point. Since the frequency of the modulated carrier changes, the duty cycle of the resulting pulse ...

Bandpass modulation techniques encode information as the amplitude, frequency, phase, or phase and amplitude of a sinusoidal carrier. These bandpass modulation schemes are known by their acronyms ASK ...
