Therefore we are concerned with the comparison of frequency and time of TV signals either via satellite or near-ground level between two remotely located pieces of equipment. In this system, the microcomputer (NEC PC-8001) widely used is equipped with its I/O devices. Separate interfaces were made for the phase comparator, the counter, and the timer. And their respective programs concerning frequency and time were also made. By making use of those interfaces and programs we can deal with speedily input data itself from the phase comparator, the counter, and the timer in agreement with output form. It was found from the output data of the microcomputer that the standard frequency deviation is of the order of 10^<-12> and the accuracy of the time comparison is almost less than 100 nano-seconds.}, pages = {15--25}, title = {マイクロコンピュータによる周波数・時刻の精密比較データの処理}, volume = {25}, year = {1983} }
