Patent ID: 8035754

Claim:
A receiver apparatus capable of receiving program signals relating to programs provided from a broadcasting station for a plurality of channels different in frequency band, comprising: a first signal processing unit configured by an integrated circuit, for applying signal processing to the received program signals; a second signal processing unit disposed on a downstream of the first signal processing unit, for applying signal processing to the signals provided from the first signal processing unit, the second signal processing unit being configured by an integrated circuit; and a control section for issuing to the first and second signal processing units a predetermined command to cause the first and second signal processing units to apply signal processing, wherein the first signal processing unit includes: a first filter unit that passes therethrough any of the program signals of a first frequency band selectively from the program signals for the channels; an amplification unit for amplifying the program signal provided from the first filter unit; a splitting unit for splitting the program signal provided from the amplification unit for every channel; a local oscillator for generating an oscillation signal of a predetermined oscillation frequency; a mixer unit for mixing the program signals of the channels as a result of splitting by the splitting unit with the oscillation signal generated by the local oscillator to generate mixed signals; a gain control unit for controlling a gain of the mixed signals generated by the mixer unit; and a second filter unit that passes therethrough any of the mixed signals of a second frequency band selectively from the mixed signals provided from the gain control unit, wherein the second signal processing unit includes: a conversion unit for converting the mixed signal provided from the second filter unit into a digital signal; a third filter unit that passes therethrough any of the digital signals of a third frequency band selectively from the digital signals provided from the conversion unit; and a demodulation unit that demodulates the digital signal provided from the third filter unit, and wherein a passing frequency bandwidth of the first filter unit can be controlled externally such that program signals of a plurality of predetermined channels are included.
