ABSTRACT:
For use in combination with a demodulator (23) for demodulating a received signal susceptible to fading into a demodulated signal, an adaptive equalizer comprises a fading detecting circuit (51) for detecting the received signal to produce a detection signal representative of a magnitude of the fading. Into a processed signal and supplied with the detection signal, an equalizer multiplier (53) processes an equalized signal produced in an equalizer section (25, 26 and 27) which is for carrying out a predetermined equalization operation. In accordance with the processed signal, an automatic gain control circuit (52) modifies the demodulated signal into a modified signal on which the predetermined equalization operation is carried out.
