IPC: G08G1/09
Filed: 1981-07-31
Abstract: PURPOSE:To prevent the occurrence of malfunction and to exclude a filter having a high Q value, by discriminating digitally the AM signal put on an FM signal. CONSTITUTION:The out-of-band component of an FM signal is removed through a primary filter of a wide band comprising an operational amplifier U1. Then the FM signal is supplied to a band pass filter comprising an operational amplifier U2. The output of the band pass filter is all injected to a noninverse input terminal of the amplifier U1. In this connection, the pass component of the band pass filter is removed out of the signal which is applied to the noninverse input terminal of the amplifier U1. Thus the input signal can be separated into two components with high efficiency. The output of a branching filter circuit 21 is shaped through a waveform shaping circuit 22, and then the information is obtained through a pulse duration discriminating circuit 24. Thus high reliability is obtained for a demodulator which is used to a traffic information system in which an AM signal is put on the FM signal.
