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.

Oscillation apparatus

An oscillation apparatus is provided with a present value generating unit for generating a present value which is monotonously increased or decreased with the passage of time; a threshold value generating unit for generating a threshold of which a value is periodically varied; a comparing and detecting unit for comparing the present value generated in said present value generating unit with the threshold generated in said threshold value generating unit; a present value reset unit for resetting the present value to a predetermined initial value whenever said comparing and detecting unit detects a fact that the present value reached the threshold; 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 said comparing and detecting detects a fact that the present value reached the threshold.
