Abstract

PURPOSE:To realize an effective demodulation of the base band signals for application other than the mormal use in the FM multiple communication by applying the output of the frequency discriminator to the constant impedance band limiter and then delivering the band limit output after amplification at the base band amplifier. CONSTITUTION:The output of frequency discriminator is applied to constant impedance band limiter 5, and the band limit output is amplified through base band amplifier 3. Limiter 5 connects the constant impedance to the output terminal of discriminator 1 to prevent the reflection over the entire base band, and as a result the deterioration of characteristics caused by reconnection at discriminator can be avoided. At the same time, the signal of the desired band can be drawn out. Thus an effective demodulation is ensured the signals of the base band excepting the base band of the normal use in the FM multiple communication.
