VARIABLE RATE PULSE GENERATING SYSTEM

摘要

A pulse generating system is disclosed wherein output pulses are provided at a rate decreasing or increasing from an initial rate with the passage of time. The output pulses are generated by a comparator responsive (1) to a first counter advanced in count by a constant rate pulse generator and (2) to a second counter which is presettable and is advanced or reduced in count from its preset count by a third counter which generates an output at each generation of a preselected number of pulses by the constant rate pulse generator.
