ABSTRACT:
An analogue to digital converter has input for receiving an analogue signal and a frequency modulator for modulating the frequency of a carrier signal in dependence upon the analogue input signal. A digital counter counts the time between successive events in the modulated signal to provide digital signals representative of the analogue input signal.
