Abstract: PURPOSE:To prevent the deterioration in a frequency stability due to temperature fluctuation by using an inverse characteristic circuit of a demodulation section of a receiver and using an AFC amplifier taking a difference between a demodulation signal and an inverse demodulation signal and amplifying it when a multi-channel FM radio equipment is intermitted at standby and an AFC loop utilizing a radio equipment reception section is constituted. CONSTITUTION:An intermediate frequency output of an FM receiver is subjected to amplitude limit by an amplitude limit circuit 12 and an AM modulation component is eliminated. A demodulation output A is obtained from the output by an FM demodulator 13 and a 90 deg. phase lead circuit 15. An AFC amplifier 19 inputs outputs of an adder circuit 18 and an FM demodulator 14 to obtain an output G. The output has a DC component decided by the output level of a reference DC generating circuit 17 and since the DC fluctuation due to temperature fluctuation of FM demodulators 13, 14 is equal, the synthesized output has always a constant DC component. That is, the demodulation of opposite phase is applied by the FM demodulators comprising the same IC and the fluctuation of the DC component due to temperature fluctuation is cancelled by synthesizing it.

Abstract: PURPOSE:To increase the number of times of reading an operation mode switch, to speedily detect the change of the operation mode switch, and to shorten the change response time by reading the operation mode switch with an interval process between scanning processes and a constant-period interrupting process. CONSTITUTION:A CPU 10 after completing one scanning process performs the interval process between scans to read out the instruction contents of the operation mode switch 50 and also set and write an operation mode in the process. Consequently, when the instruction contents of the operation mode switch 50 are altered after the timing T1 of constant-period interruption, the instruction of the mode change is detected by the reading process (T4) of the interval process. When the instruction contents of the operation mode switch 50 are altered at the timing T5 of the reading process, on the other hand, the instruction of the mode change is detected by the constant-period interruption at timing T6. The mode change is detected by the interval process between scans at the early point of time as compared with a switch read only by the constant-period interruption.

Abstract: PURPOSE:To reproduce an audio signal with excellent quality of transmission and to eliminate noise at track switching, by providing a higher harmonic suppressor filter for an FM modulation system. CONSTITUTION:An audio signal is inserted between a luminance signal FM modulation carrier and a chrominance signal low frequency conversion band through FM modulation.
