This invention concerns a pulse train generator comprising a shift register with feedback for producing an output pulse for every m clock pulses applied to the shift register stages. The feedback shift register normally has a maximal length 2 to the n power -1, where n is the number of stages. Clock pulses are applied to the shift register until an all-ONE condition is reached thereupon, m-1 additional clock pulses are applied and the states of the register stages can then be sensed. Appropriate gate circuits are added to the shift register, depending upon the sensed register states, to inhibit certain shifts and to insure that the register is returned to the all-ONE condition upon arrival of every mth clock pulse.
