[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 ...

The modem in your home does both modulation and demodulation of data signals to enable internet -- hence the name (Mo-modulator, Dem- demodulator). If that sounds too technical, let's understand ...

For more, see “How MIMO Works.” In the past, unique circuits implemented modulation and demodulation. Today, most modern radios are software-defined radios (SDR) where functions like ...

Finally, a parallel-to-serial converter translates the dibits to bits, thus producing the desired PCM signal. An alternative demodulator that's suitable for the aforementioned QPSK modulator ...
