Abstract

PURPOSE:To enable excellent operation without count error even with deficient state of input pulses and to quicken the response speed, by discriminating the presence and the phase order of multiphase pulse incoming from the state of input register and status register. CONSTITUTION:A signal from a transmitter (not shown) is input to input terminals A1-A3 of an input register 1 and led to input terminals D1-D3. The data at the input terminals D1-D3 are latched at the rise of the pulse fed to the terminal T and output to output terminals Q1-Q3. A part of the output is fed to a status register 2 and the input is latched with the rise of the clock at ''1'' level input to the terminal E. The output of the registers 1 and 2 is fed to OR circuits 3a-3c and 4a-4c to enable the detection of the forward and reverse pulses respectively. Thus, even if the state of input pulse is deficient or the pulse is reversed due to negative amount of measurements, the counter can operate in excellent manner without count error, allowing to quicken the response speed.
