1. A method for managing power in a receiver that receives a signal from a transmitter, comprising the steps of:

  • determining whether the transmitter has completed transmission of a previous signal;

    determining minimum acceptable values of one or more operating parameters of one or more of a plurality of components of a demodulator of the receiver according to an operating mode of the transmitter as determined by the demodulator and a characteristic of a received signal from the transmitter; and

    adjusting one or more of the operating parameter of the one or more components to the minimum acceptable values of the operating parameters, the adjustment made on a time slice boundary between the received signal and the previous signal;

    wherein the one or more operating parameters is at least one of a clock rate and a bit width.
