摘要
Provided is a tuner, which comprises: an amplifier for amplifying received signals; a synchronization processor for mixing the received signals with oscillating frequency signals to output intermediate frequency signals of a selected channel; an intermediate frequency signal processor for filtering and amplifying the intermediate frequency signals; a demodulator for demodulating the amplified intermediate frequency signals and detecting intensity of the signals to output a gain control signal; and an attenuator for attenuating intensity of the received signals in response to the gain control signal.
