Patent number: 4223270Abstract: 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.Type: GrantFiled: July 20, 1978Date of Patent: September 16, 1980Assignee: General Dynamics Corporation Pomona DivisionInventors: Hans-Peter Schmid, Richard S.

Patent number: 4198608Abstract: A glitch detector and trap circuit is disclosed for removing a glitch generated by a digital-to-analog (D/A) converter due to an error in one or more bits of the input digital signal. The analog output signal is delayed by one sample period. The converter output signal is then subtracted from the delayed converter output signal. This difference signal is passed through a full-wave precision rectifier. Thereafter, the notified signal is clipped at a predetermined trigger level so that a glitch will cause an output pulse. The output pulse caused by a glitch is used to operate a monostable circuit. The monostable circuit in turn, is utilized to change a track and store amplifier from its track mode to the store mode. In this manner, the track and store amplifier will not pass the glitch, but will remain at its previous setting. A rise-time delay circuit is interposed ahead of the track and store amplifier so that it will not respond instantaneously to the next sample pulse before its store mode is initiated.Type: GrantFiled: July 5, 1978Date of Patent: April 15, 1980Assignee: McDonnell Douglas CorporationInventor: William Comley
