Abstract	A very simple and effective peak detector is proposed. The system gives in real-time the position and amplitude of a peak in a digital signal to a precision better than one pixel. An FIR filter is first used to average and differentiate the signal and a linear interpolator to increase the precision of the peak position. A simulated comparison with other techniques is also given. Finally, experimental results with the use of CCD devices are presented.
