Abstract

PURPOSE:To secure easy hearing of good reproduced sound with the minimum interference distortion amount by realizing the reading of the elimination degree of the interference distortion for the interference distortion eliminating device via the deflection of the meter needle. CONSTITUTION:When FM wave signal C'(t) in the state under which the mutual interference is occurring among the FM signals is applied to FM demodulator DETdr as well as to automatic gain control circuit AGCdr at primary part DEdr of the interference eliminating device, demodulation signal e0(t) containing interference distortion component Dis(t) is supplied to DEdr from DETdr. This signal is then supplied to band-pass filter BPF1, and the distortionless output signal is supplied to BPF2. And these output are compared with each other at arithmetic circuit OC and then applied to DC amplifier DCA via integrating time constant circuit ICT and meter sensitivity switching circuit MSC to be finally supplied to meter MT after amplification.
