How an I do FM modulation of sensor input in atmega32, I read that dds can be used but I havent found good resources explaining digital FM modulation?
That would be great. Can you explain how FM modulation works?
Sure. Frequency modulation (FM) is a technique used to encode information into a waveform by varying the frequency of the carrier signal. In order to do FM modulation of sensor input in atmega32, you would need to first sample the input signal, convert it to a digital signal, and then use a DDS circuit to modulate the frequency of the carrier signal.
