Abstract
A simple nonlinear (quadratic) filter is shown to demodulate bandpass sampled AM signals efficiently. The filter is based upon a discrete ve rsion of the recently introduced Teager-Kaiser energy operator, but al so closely resembles a complex digital sampling demodulator. Such a fi lter can also be implemented in analogue circuitry.
