ABSTRACT:
In an amplitude demodulator for radio receivers, an intermediate frequency signal is converted into a digital intermediate frequency signal. The digital intermediate frequency signal is mixed into the baseband and amplitude demodulated. Either the intermediate frequency signal, or the amplitude demodulated signal, is controlled and amplified or attenuated so that the DC component of the amplitude demodulated signal is kept constant.
