TIME INTERVAL METER Russian patent published in 2005 - IPC

FIELD: measurement technology.

SUBSTANCE: second register is introduced into the meter additionally which register has data inputs connected with corresponding outputs of multiphase pulse oscillator. Outputs of the second register are connected with corresponding inputs of second coder and clock-pulse input of the register is connected with input signal terminal of the beginning of time interval to be measured. Meter also has third and fourth registers, flip-flop and inverter unit. First input of second register and outputs of second coder are connected with corresponding junior digital inputs of adder through inverter unit. Senior digital inputs of adder and its transition input are connected with logic "unit" bus. Senior digital inputs of adder are connected with corresponding outputs of the third register which has data inputs connected with corresponding outputs of pulse counter. Inverting input of pulse counter is connected with first input of multiphase pulse oscillator.

EFFECT: improved speed of operation; improved precision of measurement.
