Abstract
Abstract A clock pulse generator for word pulses is comprised of a signal generator, a distributor to divide the signal generated by the signal generator into a plurality of outputs, a plurality of parallel circuits connected to receive the divided signals, each circuit including a serially connected delay circuit and a pulser, and a mixer to combine outputs from the parallel circuits characterized in that the respective parallel circuits have equal delay time difference.

Claim 3
Dependent Claim
25 words
The word-pulse-generating device according to claim 1 wherein said parallel circuits assigned for respective bits are selectively interrupted to provide the desired binary word pulses.
Claim 4
Dependent Claim
34 words
The word-pulse-generating device according to claim 1 wherein each said pulser comprises a snap-diode pulse-generating circuit having impedance means controllable to determine the width of the pulse generated by said pulser including zero-width pulses.
Claim 5
Dependent Claim
25 words
The word-pulse-generating device according to claim 3 wherein said parallel circuits assigned for respective bits are selectively interrupted to provide the desired binary word pulses.
