Abstract
A pulse width discriminator comprises a tapped analog delay line which preferably is a charge coupled device (CCD). The taps are spaced one sample time apart along the delay line. A correlator output is obtained by summing the outputs of all taps. A pulse amplifier output is obtained by weighting and adding the signals from selected taps. The correlator output corresponds to a low-pass filter. The sample rate is at the Nyquist rate. The pulse amplifier output is a maximum for a pulse width determined by the length of the delay line (in terms of number of sample points) divided by the sample frequency. The correlator output has a maximum corresponding to the maximum of the pulse and can be used to determine the presence of a pulse. This pulse processor is also capable of handling a plurality of inputs by multiplexing them.
