The peak value of complex, bounded band-limited signals was estimated from the peak value of the samples and the oversampling rate. The errors in the reconstructed signal was bounded given small errors in the samples. Oversampling was found to provide robust recovery with small errors in the sample leading to small errors in the reconstructed signal.
