METHOD OF FORMATION 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 into which composition the data units developing two-polar signals, in particular, induction data units of a rotation frequency and the rate of flux. In the method volt-second of the area of two half-waves of each two-polar signal of the rotation frequency induction data unit is measured and compared, and at first measure area S_1k of the first half-wave and threshold value S_th1=Q·S_1K is developed where Q<1, then area S₂ of the second half-wave is measured and in the course of measuring S₂: 1) the gained quantities S₂ are compared with S_th1 and at performance of requirement S₂>S_th1 a demanded impulse is shaped or 2) additional parametre S_x=(1+Q)·S₂/2 is developed, comparing it with S_th1, S_1k and at performance of requirement S_th1<S_XK <S_1k a demanded impulse is shaped. Version of the device realising the method contains the block (1) in which by integration measuring S₁ is reached, in the block (2) value S_1k is remembered and the threshold, inverted rectifier (4), block (6) of guidances is shaped.

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