ABSTRACT:
A device and method for measuring the rate of change of a pulse train from a transducer includes first counter which counts the number of pulses in a first fixed frequency of pulse train during each interval between the signal pulses. A divider receives the count generated in the preceding interval and divides the frequency f.sub.1 of a second fixed frequency pulse train by this count. This divided pulse train is counted by a second counter for the duration of each interval to provide a ratio of the change in duration to the preceding interval's duration.
