Suppose in my system, I have a signal that is being reflecting back from a sensor, the signal has both amplitude and phase variation as the sensor is moving on the Device Under Test. I want to cancel the amplitude variation of the reflected signal, and someone told me that "Sine wave and huge amplification will results in a square wave with the zero crossing maintained(phase information is maintained)." Can anyone elaborate this further please? If I feed this reflected signal to a very high gain amplifier, how does the amplitude+phase varying signal at the input of the amp look like at the output of the amp?
