Abstract:
1. A method of controlling power consumption of a tuner circuit comprising the steps of: providing an input port for receiving an RF signal including information modulated therein upon a plurality of channels and being within a predetermined frequency band; providing a tuner signal conditioning circuit for conditioning the RF signal comprising; superheterodyne circuitry including the tuner signal conditioning circuits for processing any signals coupled thereto via the output port and discriminating the received information signals within a selected channel; determining from the received RF signal an approximate linearity requirement and an approximate gain requirement; and, performing one of increasing the gain of the tuner signal conditioning circuits and decreasing the linearity of the tuner signal conditioning circuits and decreasing the gain of the tuner signal conditioning circuits and increasing the linearity of the tuner signal conditioning circuits; and, controlling power supplied to different circuit portions of the superheterodyne circuitry and tuner signal conditioning circuits, the power supplied being one of enabling and disabling of power provided.
