摘要: A digital logic circuit for use with an incremental positioning encoder is presented. The converts two quadrature pulse train signals, generated by position type encoder, to a counting CLOCK signal and UP/DOWN count signal. signals are transmitted on counters generate clock the information. utilizes gate delays detect edge of No external clocks or comparators nested. design, relying propagation delay gates, keeps simple more reliable.
