ABSTRACT:
An information signal processing system for use with a pattern recognition system which includes a converting device for converting information signals of an object or pattern to be recognized into electric signals including a sampling circuit for sampling the electric signal from the converting device, a circuit receiving the electric signal and producing a signal to be supplied to the sampling circuit to determine the sampling time, and a computer receiving the output signals from said sampling circuit and sequentially comparing them with reference signals stored therein. In this case, the information signal processing system includes a circuit which receives the electric signal from the converting device and produces a signal which approximates the electric signal. This approximated signal is supplied to the sampling circuit.
