Abstract

PURPOSE: To realize not less than three kinds of broadcasting different in tone intermediate frequency by changing turning elements of a frequency mixer circuit over by connecting a switching method to output terminals of several tuning input circuits.
CONSTITUTION: To the input terminal of frequency mixer circuit 5 which converts tone intermediate frequencies different in broadcasting system into a fixed tone intermediate frequency, output terminals of input tuning circuits 6, 6' and 6" are connected via input diodes 10, 10' and 10". Between power supply 9 and the output terminals of tuning input circuits 6, 6' and 6", change-over switch 12 is connected and tuning elements of frequency mixer circuit 5 are changed over corresponding to the switching of this switch 12. Consequently, an output signal from frequency mixer circuit 5 is applied to output tuning circuit 7, and a signal of a specific frequency can be obtained from output terminal 8.
