Coincidence circuits for nanosecond range

Two nanosecond coincidence circuits are described. The first has four coincidence inputs and one anticoincidence input and is distinguished with the presence of channels of digital control by switching on of inputs and regulation of output pulse duration. The second coincidence circuit represents 16 input majority coincidence circuit with digital selection. It differs in that respect that does not require shaping of input pulses in duration; its resolution time can be both more and less than input pulse duration
