Abstract
An apparatus and method for removing a transient exponential noise signal from a sinusoidal signal. The effects of the transient are removed by sampling the sinusoidal signal, averaging the transient over a time interval corresponding to an integral number of cycles of the sinusoidal signal, and subtracting this average from the sample at the midpoint of the time interval. The result is a compensated sinusoidal signal wherein the effects of the transient have been removed. The time interval is progressively moved ahead to produce a complete compensated signal by subtracting the average of the exponential from the value thereof at the midpoint of each successive time interval.
