Abstract

PURPOSE:To eliminate completely the disturbance signal even at the high-channel reception time through a simple constitution by varying the trap frequency in accordance with the reception frequency for the TV picture receiver. CONSTITUTION:The tuning capacity is formed by capacitor 24 and 26 of reception signal tuning circuit, coil 16 and variable capacity diode; and the trap circuit of the image signal of the reception signal if formed with the parallel circuit comorising diode 32, coil 16 and capacitor 26 and the series circuit comprising capacitor 24. Thus, the capacity of diode 32 varies to perform the tuning by controlling the voltage supplied to terminal 52 at the high-channel reception time. At the same time, the trap frequency also varies for the trap circuit with variation of diode 32.
