[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 ...

Varying the voltage of a carrier or a direct current in order to transmit analog or digital data. Amplitude modulation (AM) is the oldest method of transmitting human voice electronically.

The following overview should give you enough of an understanding about the basics of RF modulation to select the appropriate hardware for your next project. Three of the most common digital ...

If you are using a digital synthesiser, you may want to consider very slightly adjusting the tuning, so that the pitches are not identical. If your synthesiser has an analog impurity control ...
