  • Tuner arrangement
    Patent number: 7437134
    Abstract: A tuner arrangement is provided comprising one or more tuners. Each tuner has two or more frequency changers, each comprising a mixer and a local oscillator. A controller controls the local oscillators in response to receipt of a channel select request. The controller determines the nominal frequencies of the local oscillators for tuning the selected channel and then performs a calculation to determine whether any beat frequencies between harmonics greater than the first harmonic of the local oscillators lie within the frequency band at the tuner output occupied by the selected channel. If so, the controller shifts the local oscillator frequencies so as to move the potentially interfering products outside the utilised band and then tunes the local oscillators appropriately.
