TIME-INTERVAL METRE Russian patent published in 2010 - IPC H03D13/00 G04F10/04 

FIELD: physics; radio.

SUBSTANCE: time-interval metre is designed for taking frequency and time measurements in radio measuring devices. The time-interval metre comprises series-connected reference generator (1) and a cyclic pulse counter (2), N request channels, each of which includes memory units (3₁-3₂) with outputs combined and connected to the corresponding input of an information processing device (4), a unit for generating and fixing reference frequencies (5), series-connected switch (6), with number of outputs equal to number of request channels N, and a control unit (7), two pulse counters (8₁-8₂) and a control trigger (9) in each of the N request channels, and a unit for stopping counting and preliminary set up of a decade (10). In the version of the device there is a channel for measuring time-interval, duration and period (11). The control unit (7) is made with auxiliary (N+1) and (N+2) outputs, and the information processing device (4) with an auxiliary (N+1) (information) input. The device is essentially made in form of a single complex-functional block on a large integrated circuit of the K1897AIT type.

EFFECT: reduced measurement errors, faster information output, possibility of measuring single (random) intervals, duration and period of recurrent pulses with averaging.
