Patent ID: 7333155

Claim:
A circuit for tuning a television channel comprising: a plurality of filters, implemented in silicon, for receiving a television signal comprising a plurality of television channels, wherein a television channel comprises a picture carrier (F p ), a sound carrier (F s ) and a color sub-carrier (F sc ) signals for tuning a television channel, and for attenuating frequencies out of band of said television channel; in-phase—quadrature phase (“I, Q”) demodulation circuit, coupled to receive a filtered television signal from said filters and for generating a baseband television signal; and post Nyquist filter, coupled to receive said baseband television signal from said I, Q demodulation circuit and for rejecting signals in adjacent channels, to generate a Nyquist slope, and for extracting a picture signal content from said picture carrier (F p ) and color sub-carrier (F sc ) signals and a sound signal content from said sound carrier (F s ) signal.
