Abstract
An oscillation apparatus is provided with a signal input unit for supplying a pulse sequence consisting of pulses sequentially continuously occurred; a state quantity generating unit for generating state quantity having a value which is monotonously increased with the passage of time; a state quantity transition unit for transferring a value of state quantity in the course of generation in said state quantity generating unit to a value changed by a predetermined amount in a varying direction of the value of the state quantity with respect to a present value of the state quantity, whenever one pulse is fed from said signal input unit to said state quantity transition unit; a state quantity reset unit for comparing the present value of the state quantity generated in said state quantity generating unit with a predetermined threshold value, and resetting the present value of the state quantity generated in said state quantity generating unit to a predetermined initial value when the present value reaches the threshold value; and a signal generating unit for generating sequentially signals of which a period is defined by a time interval of timing-to-timing in which the state quantity is reset to the initial value.
