Patent ID: 8520148

Claim:
A circuit module for processing a radio frequency broadcast signal, comprising: an input terminal configured to receive said radio frequency broadcast signal; a tuner circuit in operable connection with said input terminal to receive said radio frequency broadcast signal therefrom, said tuner circuit being configured to convert said received radio frequency broadcast signal into at least an intermediate frequency signal; a filter in communication with said tuner circuit to receive said intermediate frequency signal therefrom, said filter being configured to define frequency characteristics of said intermediate frequency signal to produce a frequency characteristics defined intermediate frequency signal; a demodulator in communication with said filter to receive said frequency characteristics defined intermediate frequency signal therefrom, said demodulator being configured to produce at least a video signal based on said frequency characteristics defined intermediate frequency signal; and an output terminal in communication with said demodulator to receive said video signal therefrom, said output terminal being configured to output said video signal at an output level to an input of an external circuit, said filter, to compensate an attenuation of a high frequency component, among the defined frequency characteristics of said frequency characteristics defined intermediate frequency signal, when said output terminal outputs said video signal to the input of said external circuit, boosts a gain of the high frequency component of said frequency characteristics defined intermediate frequency signal by a predetermined amount to compensate the attenuation, and wherein said output terminal outputs said video signal to the input of the external circuit without using an external buffer between said output terminal and said external circuit.
