METHOD OF GENERATING PULSES FROM SIGNALS OF ROTATIONAL FREQUENCY INDUCTANCE PICKUP Russian patent published in 2010 - IPC H03K5/153 G01R23/02 

FIELD: physics.

SUBSTANCE: method is based on evaluation of parametres of two half-waves of opposite polarity of each bidirectional signal of a rotational frequency inductance pickup and generation of the required pulse based on the evaluation results. According to the invention, parametres of two half-waves of opposite polarity of each bidirectional signal of the rotational frequency inductance pickup are evaluated by comparing the signal of the rotational frequency inductance pickup with half of its minimum possible amplitude and if the former is greater, a time interval is formed which results from the expected onset of the maximum of the second half-wave of opposite polarity of the signal of the rotational frequency inductance pickup. The signal of the rotational frequency inductance pickup is then compared with half of the minimum possible amplitude of the half-wave of opposite polarity and if the former is greater, the required pulse is generated.

EFFECT: higher noise immunity with respect to low-frequency periodic bipolar and pulse noise.
