FM INTERFERENCE PREVENTION CIRCUIT IN SIX CHANNEL OF TV RECEIVER

摘要

A circuit prevents the interference of FM radio broadcasting with TV channel 6 broadcast. The circuit comprises a microprocessor for receiving channel selecting data output from a data input device and outputting phase locked loop (PLL) data. A control signal generating device receives the PLL data and generates a control signal to control an FM trap operation. A trap operation controlling device then controls the operation of an FM trap according to the control signal. According to the present invention, TV channel 6 broadcasting can be received without noise.
