Abstract
In a demodulating circuit, for example, for demodulating an amplitude- or frequency-modulated signal, analog-to-digital converted values are obtained at a plurality of sampling points in each cycle of the modulated signal, such converted values are integrated to provide a calculated integration value for the respective cycle, and the calculated integration value is compared with a maximal integration value derived in the same manner so as to obtain the demodulated output.
