ABSTRACT:
An analog signal analyzer is described for counting the number of significant peaks and valleys in an analog signal. The analyzer includes an analog-to-digital converter, a signal-amplitude change-detector, a presettable counter presettable by a threshold-rate-factor number "n", and a logic circuit which detects a reversal in the direction of the signal-amplitude-changes between successive sampling times, and down-counts the counter each sample time in which the signal-amplitude changes continue in the same direction until "n+1" counts are reached. At that time it produces an output count, reloads the counter with the number "n", and conditions the circuit for thereafter down-counting the counter only when the signal-amplitude-change is in the reverse direction.
