ABSTRACT:
The widths of pulses in an incoming pulse train are monitored by successively measuring the duration of the pulses in the pulse train and enabling a timing device when the duration of any of the pulses is more than a preselected magnitude. The timing device is reset and restarted when the duration of any of the pulses is greater than the preselected magnitude. An output signal, indicative of an acceptable condition, is produced when the timing device indicates the expiration of a predetermined time delay. An output signal, indicative of a non-acceptable condition, is produced when the duration of a pulse in the incoming pulse train exceeds the preselected magnitude. This invention encompasses both the pulse width monitoring method and circuits which perform this method.
