Abstract
The present invention relates to an apparatus for producing a succession of pulses corresponding to the succession of pulse beats of a person. The apparatus has a pulse detector and at least one stage subsequent to the pulse detector to suppress disruptive influences. The invention is characterized by a voltage-controlled pulse generator which is controlled by a comparator. The comparator compares the contents of two memories of which the first stores the pulse coming from the pulse detector and the second stores the pulse appearing at the output of the pulse generator.
Claims8
An apparatus for producing a succession of pulses corresponding to the succession of pulse beats of a person, said apparatus having a pulse detector and at least one stage means, arranged subsequent to said pulse detector, for suppressing disruptive influences, comprising:
- a voltage-controlled pulse generator,
- first and second memory means,
- a comparator means for controlling said pulse generator and for comparing contents of said first and second memories, whereby disturbances in the form of missing pulses may be suppressed,
- said first memory being coupled to the output of said pulse detector and having means for storing a pulse coming from the pulse detector, and
- said second memory being coupled to the output of said pulse generator and having means for storing a pulse appearing at an output of the pulse generator.
