Hi all,
I have an analogue signal, sinusoidal shape, whose amplitude is continuously changing. The signal is always greater than the input. What I need to do is attenuate this signal, without causing distortion so that the output has a constant amplitude.
I first thought about using a digital pot, however this requires the intervention of a microcontroller. Is there a way to achieve the same purpose using only components such as an opamp or passives?
