Abstract
PURPOSE:When the number of clocks which is equal to the contents of a data latch circuit is counted by counting clocks from a clock oscillator via a counter, the counter sets to an initial value itself, so that it can be used as NCO which never misreads digital codes even when the digital codes to be applied to a numerical control oscillator (NCO) are entirely changed at any time at the numerical counter newly counting the same number of clocks as the contents of the data latch circuit.
