Abstract
A processing pulse control circuit for use in treating indeterminate signature increments in an apparatus producing RPT signature analysis of digital circuits. A circuit to control clock pulses to processing devices is provided. The circuit includes a counter to produce a count corresponding to the number of clock pulses received, and also a memory which stores clock count values where indeterminate signature increments will be encountered. A comparator compares the actual clock count values with the stored clock count values to produce a control signal. In response to this control signal, clock pulses are normally allowed to pass to a processing device during clock pulse counts at which determinate signature increments are encountered, but are blocked where indeterminate signature increments are encountered.
