At very high frequencies, the response of the rectifier will fall off. The roll−off will be more pronounced at lower input levels due to the increasing amount of gain required to switch between conducting. The rectifier frequency ...

The distortion is not affected by the magnitude of the gain control current, and it does not increase as the gain is changed. This second harmonic distortion could be eliminated ...
