Abstract
A numerical control type oscillator whose output oscillation frequency is controlled depending on input numerical data, comprises: first accumulation means for accumulating a first set value which is set depending on the input numerical data with a first frequency and sequentially outputting the accumulated value; second accumulation means for accumulating a second set value which is set depending on the input numerical data with a second frequency and varying the first set value by a predetermined value temporarily when the accumulated value reaches a predetermined maximum value; and frequency generation means for outputting a frequency depending on an output of the first accumulation means as an oscillation frequency.
