ABSTRACT:
An amplifier system has a control circuit. An amplifier is coupled to the control circuit and has a controllable gain. A controllable input impedance circuit is coupled to the control circuit. When the gain of the amplifier is changed the controllable input impedance circuit's impedance is adjusted, so that the input impedance to the system remains essentially constant.
