1. A method for circuit gain adjustment, the circuit having a signal with power, the method comprising the steps of:

  • varying the circuit gain a predetermined amount;

    determining a magnitude of a change in the power of the signal in response to the varying of the circuit gain; and

    adjusting the circuit gain in response to the magnitude of the change in the power of the signal, the step of adjusting comprising the steps of;

    decreasing the circuit gain when the magnitude of the change in the power of the signal is greater than a predetermined threshold; and

    increasing the circuit gain when the magnitude of the change in the power of the signal is less than or equal to the predetermined threshold.
