Abstract

A multichannel meter of time interval in pulse series comprises information reception RS flip-flops, time counter which inverting input and R reset input are connected to the bus of time pulses and to the bus of reference pulses, correspondingly, second counter which inverting input is connected to the bus of clock pulses, and Q-outputs of information reception RS flip-flops are connected to A address inputs of multiplexor which data D-inputs are connected to Q-outputs of corresponding information reception RS flip-flops which S-inputs are connected to corresponding input buses, RS flip-flop which S-input is connected to the bus of reference pulses. The meter additionally comprises n DC flip-flops and n EXCLUSIVE OR gates, buffer register, wherein C-inputs of DC flip-flops are connected to the bus of reference pulses, and D-inputs are connected to corresponding input buses and to first inputs of EXCLUSIVE OR gates, to which second inputs Q data outputs of DC flip-flops are connected, data outputs of EXCLUSIVE OR gates are connected to S-inputs of information reception RS flip-flops to which R-inputs the bus of reference pulses is connected. Q-outputs of T-bit time counter and Q-outputs of the information reception RS flip-flops are connected to data D-inputs of the buffer register, C-input of the buffer register is connected to gating line of output data bus and to multiplexor input through AND gate, overflow output of P+T-bit time counter and Q-outputs of the buffer register are accessible for connection of microcomputer.
