PURPOSE: A very high frequency high band noise suppressing device is provided to eliminate an FM radio signal which can influence a high frequency high band signal, thereby transferring a signal from which the FM radio signal is eliminated to a digital tuner. CONSTITUTION: A trap filter unit(120) traps a band signal among inputted signals. When a high band signal is transmitted to the trap filter unit, a trap activating unit(110) activates the trap filter unit. The trap filter unit includes an inductor and a capacitor. The trap filter unit traps 90MHz~100MHz band signals. The trap activating unit includes a resistor and a diode. |
