Abstract
Apparatus for generating an output signal having a frequency and duty cycle controllable in response to a pair of binary control words. The apparatus includes a pair of counters which are alternately enabled for counting high frequency clock pulses for respective time durations determined according to the two binary control words. A bi-stable device is controlled by the counters for developing the output signal which alternates between two levels for time durations corresponding to the time periods during which the two counters are enabled. The frequency and duty cycle of the output signal are therefore controllable by suitably adjusting the values of the two binary control words.
