DEFINITION

Classification: 368/119

Plural:

(under subclass 118) Subject matter having two or more periodic or periodically varying signal generating means with the periods of the signals of at least two of the generating means representing unit intervals of time.

(1) Note. The unit intervals generated by the plural generating means of this subclass need not be of equal duration. An example of time measuring means including plural generators of signals having different periods is the "vernier" type of time measuring means.
