DISCRETE DELAY LINE FOR PULSE SIGNALS Russian patent published in 2009 - IPC H03H7/30 H03K5/13 

FIELD: physics; control.

SUBSTANCE: invention relates to pulse, digital engineering and can be used in computers, automation, measuring devices, radar, communication devices etc, for making a discrete line for delaying output pulses relative input pulses within its duration limits in accordance with an incoming binary code. The device has an inverter gate (3), multiplexer (MX) (5), the input of which is connected to the input (6) which blocks/allows generation of output pulses of pulse generator (8). The output of pulse generator (8) is connected to the complementing input of an n-bit pulse counter (9), n outputs which are connected to n inputs of a digital comparator (K) (10), the other n inputs of which are connected to n outputs of an n-bit register (11), which assigns the code value required for delaying input pulse signals. The output of the comparison result of K (10) is connected to the complementing input of an output single-bit pulse counter (12), one of the outputs of which is connected to the control input of MX (5). The said delay line is distinguished by employing a binary counter as a generator of the time intervals for delaying the front and droop of the input sequence, which, coupled with delay of fronts and drooping of input pulses, allows for making a compact integrated circuit of quasicontinuous delay line for input pulses.

EFFECT: reduced area occupied by the integrated circuit; minimum possible nanosecond increment value of the delay line.
