ABSTRACT:
A device for determining the average period of a low-frequency periodic sal comprises a counter receiving stepping pulses from a high-frequency pulse generator and resetting pulses from a phase-angle detector monitoring the periodic signal. A shift register is loaded with the count of the counter in response to each pulse generated by the detector, an adder at an output of the shift register emitting a signal coding the sum of the contents of this register. Another shift register is loaded under the control of the detector with the output sums of the adder and has a first and a last storage cell connected to a substractor which emits a signal indicating changes in average period. Further registers and summing circuitry may be inserted between the adder and the additional shift register for increasing the number of periods taken to form each average-period estimate.
