Abstract

PURPOSE:To secure the high accuracy and high stability for the digital control by redoubling the unit number of the detection pulse by means of the electronic circuit and the computer when the rotational speed pulse given from the detector is sampled. CONSTITUTION:The rotational frequency detection signals are counted 4 for one sampling period and then loaded to register 6. At the same time, the pulse intervals of the rotational frequency detection signals are counted 5, and then both the sampling synchronous signal in the course of the pulse interval of the rotational frequency detection signals and the pulse interval count signal of the rotational frequency detection signals are loaded to register 7. And also count value 5 is loaded to register 8. Then output data alpha, beta and gamma of registers 6-8 are processed at CPU12 and via the operation equation of ''(alpha+beta/gamma)XK'' (K: optional increase multiple). Thus the output pulse of the K-fold frequency which is similar to the rotational frequency detection signal is obtained.
