Abstract
An apparatus and method for characterizing an amplifier transmitting a band limited signal using a sample of the input signal to the amplifier and a sample of the output signal from the amplifier, where the output signal is sub-sampled. The sub-sampling frequency is chosen such that images of the band limited signal do not overlap. The input signal and the output signal in a polar format are processed to determine characteristics such AM/AM and AM/PM conversion nonlinearities.
