PURPOSE:To perform sterephonic reproduction with relatively high quality, by detecting an interferenece signal to disturbing a received signal demodulated by an FM demodulating means and putting the interference signal eliminating means in operation. CONSTITUTION:When an interference signal is outputted from the FM demodulating circuit 2 together with the received signal, a interference signal detecting circuit 6 and a circuit connection control circuit 7 operate to obtain a left and a right signal having relatively high quality of reproduction in terms of a sense of hearing which are passed through an antibuddy filter 4, multiplex stereophonic circuit 3, and a high blending circuit 5. When only the received signal is outputted from the FM demodulating circuit 2, said circuits 6 and 7 operates to obtain a left and a right signal of high reproduction quality passed through the multiplex stereophonic circuit 3. |
