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

FIELD: physics.

SUBSTANCE: device has two comparators, one connected directly and the other through an inverter to an input signal source. The device also has a reference signal source whose outputs are connected to inputs of the comparators, a frequency metre whose input is connected to the output of the second comparator, a device for measuring rate of change of frequency whose input is connected to the output of the frequency metre, the control input of the reference signal source, and a timer whose start input is connected to the output of the first comparator, the first control input is connected to the output of the second comparator, the second control input is connected to the output of the device for measuring rate of change of frequency, the third control input is connected to the output of the frequency metre and the outputs are connected to control inputs of the comparators respectively.

EFFECT: increased noise immunity.
