SU593221A1 - Time-pulse device for raising signal ratio to fractional power - Google Patents

Description

the second and third input key elements 4.5 and 6, integrators 7, key elements 8 of the initial setup, clock generator b, comparison unit 10, additional key element 11, output integrator 12 and device output 13. Let the signals X (t), y (t) H2 (t and at the outputs of the input key elements 4.5 to 6) act on the inputs 1,2 and 3 of the device for a given time interval. The beginning of the time intervals corresponds to the appearance of the leading edge pulses from the clock oscillator 9. The clock oscillator 9 generates pulse pulses during which the key elements of the 8-unit initial conditions for VIY are open, and the integrators 7 are in the working state. At the outputs, the inputs of the key elements 4 (5 and 6 have certain values input signals. x (. .dt); V (i) e. (t) ZCt) "" j. CC) AND "1,2, ... | 1 during the pulse of the clock generator rattor, 9 .. The clock generator 9 controls the work of the integrators 7 and the output integrator 1 The integrators 7 integrate the input signals Ql5i (t) are only once, how many integrators are in series, i.e. HHT- xJ J K / f Mx H since Q LS) in the interval, (О, -) was a constant value. K is the constant of integration, and the sign depends on the number of integrators. At the moment of comparing the signals at the input of the lO, which come from the output of the last integrator 7 and c into the course of the second input key element 5, block 10 is triggered, at the output of which a signal is formed that closes the additional key element 11, and to the input of the output integrator 12 : v. “can% t. "Hp During the impulse from the clock generator 9, at the output 13, a voltage is generated - J8b., T 5i - az. Since at the moment of the comparison - {O-a and a - D about substituting this value into the formula (2), we that: s. And S 7. 1 II-, Lh Bb.x. ; - constant integration of the system. Investigations of a prototype device showed that with the number of integrators equal to eight, the error does not exceed 0, 01%. Thus, in the proposed device, the range of the indication of the degree to the increased accuracy is expanded. and 3 about b Formula of time and Time-impulse device for raising to a fractional degree of signal ratio, containing / 1 integrators and output integrator, between the input and output of each of which the key element of the initial conditions setting is included, the input of the first integrator the key element is connected to the first input of the device, the second and third input key elements, the clock generator, the output of which is connected to the control inputs of the input key elements and the comparison unit, which differs in that increase the range of the indicator, the degree and increase of accuracy, an additional key element is inserted in it, the control input of which is connected to the output of the comparison unit, the first input of which is connected to the output. "(the th integrator, and the second input through the second input of the device, the third input of which is connected through the third input and the additional key elements connected in series to the input of the output integrator, the output of the clock generator is connected to the control inputs of the key evyh elements set initial conditions, and the yield of each; n gingegratorov except
