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

FIELD: radio engineering.

SUBSTANCE: method comprises the following steps: measuring amplitude A(i) of the positive polarity half-wave of each i-th signal of a rotational frequency inductive sensor and if A(i)≥A_min, in order to generate pulses, two heteropolar thresholds are generated, which immediately follow the measured half-wave and equal to u_port1,2(i+1)=±γ-A(i); if A(i)<A_min one of the thresholds is set equal to u_port1,2(i+1)=±A_min, where A_min is the possible minimum half-wave amplitude of the signals of the sensor, coefficient γ<1; when the first half-wave signal reaches the first threshold u_port1 pulse generation is started, and when the second half-wave signal reaches the second threshold u_port2 pulse generation is ended. Upon the arrival of each next sensor signal, the cycle for generating the required pulse is repeated.

EFFECT: high noise-immunity of generating pulses.
