Patent ID: 7079196

Claim:
A television tuner comprising: a tuning circuit which tunes with a television signal within a prescribed receiving frequency band; a high frequency amplifier which amplifies the television signal; a mixer which converts the television signal into an intermediate frequency signal; and an oscillating section which supplies a local oscillation signal to the mixer, wherein the tuning circuit is made up of an inductor and plural capacitors; wherein at least one of the capacitors is selected and connected in parallel with the inductor; wherein the oscillating section is made up of at least plural oscillators which are included in an integrated circuit; wherein in the integrated circuit, each of the oscillators has a variable capacitor to vary a frequency of the local oscillation signal; wherein groups into which the receiving frequency band is divided correspond to the oscillators on the basis of one oscillator per group; and wherein each of the oscillators generates local oscillation frequencies depending on television signals in the corresponding group.
