METHOD AND APPARATUS FOR ELABORATING AND PROCESSING TWO DISTINCT PULSE TRAINS CARRYING INFORMATION

摘要

A system for generating and processing pulses representing information, from two pseudoperiodic analog signals along two interconnected channels. Each pseudoperiodic signal is generated by a separate magnetoresistor and is converted in an associated channel into two series of pulses. Conversion is effected by means of threshold switching circuits which control the operation of a bistable flip-flop via a combining circuit. The output of the bistable flip-flop in each channel is cross-connected to one input of a combining circuit in the other channel, the other input of which is a low threshold signal corresponding to the pseudoperiodic signal fed to that channel. The gate produces the logic product of its inputs which drives a flip-flop. The output of the flip-flop is terminated by a reset pulse derived from a zero reset stage.
