We'll now move on to consider the microphone input subsystem.
Is the output from the microphone an analogue or a digital signal?
The output from a microphone is an analogue electrical signal. Just as sound in the air involves continuous pressure variations over a continuous range, so the voltage from the microphone varies continuously over a continuous range.
Because I am considering here a digital camcorder, the analogue audio signal will be converted to a digital signal, and this is the main function of the microphone input subsystem. The digital audio signal might also be compressed, and put into a standard format.
