Abstract : The patent describes a device for producing a range of precisely known pulse widths by digital decoding. A coded signal representative of the duration of a desired pulse is stored in a register and its leading edge is used to turn on a flip-flop. A stable high frequency pulse source supplies the input to a counter which provides output pulses representative of ten microseconds, one microsecond, and one tenth microseconds. These output pulses are fed into a second register whose output is compared to the output of the first register. When the contents of the two registers are equal the flip-flop is turned off, thereby terminating the pulse.
