Abstract
A translator system which includes circuitry for differentiating between normal interval timing pulses and power loss pulses on meter telemetry recordings. The pulses are recorded with a different waveform and are applied to wave-shaping circuitry which produces pulses corresponding to the time interval pulses which are longer than the pulses produced which correspond to the power loss pulses. A pulse duration recognizing circuit distinguishes between the pulses of different duration and provides a pulse output at one of two terminals depending on which pulse type is recognized. Pulses corresponding to the time interval pulses are transferred to the analyzing circuits of the translator. A masking circuit prevents recognition of a power loss pulse except during a predetermined time interval which corresponds to the only time such a pulse may correctly exist on the recording. Circuitry is included which informs the analyzing circuits of the translator when a power loss pulse is properly recognized. Means is also included for manually or automatically programming the translator to correctly read meter readings made with or without the capability of including power loss pulses on the recording.
