ABSTRACT:
The pulse signal generator produces a repetitive pulse output signal consisting of repetitive pulse groups which may have either constant pulse intervals or staggered pulse intervals. Each pulse in the group also has an adjustable pulse width and may be time referenced to a clock pulse signal. The pulse generator employs cascaded stages of individual pulse generators: one stage for each pulse in the group. The first stage generates the first pulse in each group of n pulses and additionally controls the pulse group repetition interval and the pulse width of each pulse.
A first counter/comparator generates a first start-pulse, when it counts N.sub.1 clock pulses. The start-pulse resets the first counter and triggers an output bistable (multivibrator) circuit, which initiates the leading edge of the first output pulse of the group. When N.sub.2 clock pulses are registered by a second counter, its associated comparator generates an "end-pulse" to reset the second counter and trigger the bistable circuit a second time. The second change of state of the bistable circuit completes the first output pulse and also disables the second counter until another start-pulse retoggles the bistable circuit.
The pulse generator produces the other n-1 pulses by generating successive delay trigger pulses to retoggle the bistable circuit of the first stage. Other cascaded pulse generator stages produce the delayed trigger pulses. Each cascaded stage receives the first start-pulse signal and generates its own start-pulse signal a predetermined time interval, .DELTA.t, after receiving the first start-pulse. Each stage has a different programmed time interval .DELTA.t.
