Signal processing to compensate for gain control output spikes caused by steps in a digital step attenuator. A method includes receiving a changing power input signal at a receiver. The method includes determining that a change in power of the input signal will cause a step attenuator to change its attenuation in a step of a predetermined amount. The method further includes based on determining that the change in power of the input signal will cause a digital step attenuator to change its attenuation in a step of a predetermined amount, causing a variable attenuator to change its attenuation by an amount related to the predetermined amount at a time coinciding with a time when the step attenuator changes its attenuation by the predetermined amount. The method further includes outputting a gain-controlled output signal resulting from applying the step attenuator and the variable attenuator to the changing power input signal.
