And lots of pretty graphs don’t hurt either ... bandwidth-efficient since it only outputs on a narrow frequency band. However, ASK modulation is badly affected by interference, which limits ...

[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 ...

Amplitude modulation (AM) is also widely used to alter a carrier wave to transmit data. For example, in AM radio, the voltage (amplitude) of a carrier with a fixed center frequency (the station's ...
