METHOD OF GENERATING PULSES FROM SIGNALS OF ROTATIONAL FREQUENCY INDUCTIVE SENSORS Russian patent published in 2012 - IPC H03K5/153 

FIELD: information technology.

SUBSTANCE: method comprises the following steps: measuring and comparing volt-time area of two half-waves of each bipolar signal of a rational frequency inductance pickup, wherein pulse generation threshold values are preset equal to S_pf1=(0.3-0.75)·S_pr.min1 and S_pf2=(0.3-0.075)·S_pr.min2, where S_pr.min1 and S_pr.min2 are the minimum permissible values of volt-time areas of the first and second half-waves of the signals, respectively; when measuring the area of the first half-wave of the signal, the obtained values of S₁ are compared with threshold values of S_pf1 and once the condition S₁≥ S_pf1 is satisfied, the required pulse is generated, after which during measurement of the area S₂ of the second half-wave, the obtained values of S₂ are compared with threshold values of S_pf2, and generation of the required pulse is stopped once the condition S₂≥ S_pf2 is satisfied.

EFFECT: high accuracy of repeating with generated pulses the duration of the periods of signals of rotational frequency inductive sensors, simple algorithm of generating pulses.
