SHAPER OF IMPULSES FROM SIGNALS OF INDUCTION DATA UNITS OF ROTATION FREQUENCY Russian patent published in 2009 - IPC H03K5/153 

FIELD: physics.

SUBSTANCE: invention can be used in systems of self-acting measuring, guidance and emergency protection having the data units developing two-polar signals, in particular, induction data units of a rotation frequency and the rate of flux enter. Volt-second of the area of two half-waves of each signal of the induction data unit of a rotation frequency are measured and compared in the device, and at first the S_1K area of the first half-wave is measured and threshold value S_th1=Q·S_1K is developed where Q<1 then S₂ area of the second half-wave is measured and in the course of measuring S₂ additional parametre S_x=(1+Q)·S₂/2 is developed, its peak quantity S_XK is compared to the threshold values S_th1, S_1K and at performance of requirement S_th1<S_XK<S_th2 a demanded impulse is developed. The device contains two integrators (3, 16), peak detector (4), inverting operational amplifier (15), five threshold devices (1, 7, 10, 12, 13), three keys (2, 8, 17), two devices AND (11, 14), two univibrators (18, 19) and three resistors (5, 6, 9).

EFFECT: increase of reliability, noise stability and accuracy of recurring by shaped impulses of duration of continuances of following of signals of induction data units of rotation frequency.
