Amplitude Recovery of Saturated Sinusoidal Signals
A commonly encountered problem in sensing circuits is the saturation of sinusoidal signals. This arises due to limitations in the gain and operating voltage of analog circuits. A simple and novel method is presented here for recovering the amplitude of signals that have been clipped or saturated. The method is based on keeping track of the number of sample points that are not saturated and then relating it to the amplitude of the signal. The method shows high linearity up to 30 times the saturation voltage as found from simulation. The method can also be used to recover the amplitudes of non-sinusoidal but periodic signals.
