Abstract

A totalizer receives the output signals from two different sources, each generating signals representative of a measured event, such as the consumption (or transmission) of electrical power. The totalizer generates a train of recording pulses at a predetermined "offset" repetition rate. The totalizer increases the repetition rate of the recording pulses above the offset rate in response to an increase in the repetition rate of signals received from one of the sources; and it decreases the repetition rate of the recording pulses below the offset rate in response to an increase in the repetition rate of signals received from the other source. Thus the totalizer provides a bidirectional capacity in that it records events from two sources on a single data channel.
