Abstract:
An oscillation apparatus, comprising:signal input means for receiving an external pulse train;state quantity generating means for generating a state quantity having a value which is monotonously increased with the passage of time;state quantity transition means which responds to a pulse from said signal input means by transferring a predetermined transition value to said state quantity generating means, wherein said state quantity generating means changes the value of the state quantity in response to the transferred predetermined transition value;state quantity reset means for comparing the present value of the state quantity generated in said state quantity generating means with a predetermined threshold value, and resetting the present value of the state quantity generated in said state quantity generating means to a predetermined initial value when the value reaches the threshold value; andsignal generating means for generating sequential signals which define periods having corresponding time intervals, such that said state quantity generating means resets the value of the state quantity to the predetermined initial value in response to the sequential signals,wherein said state quantity generating means generates the state quantity, which varies in value from the initial value toward the threshold value, while a variation rate of the value is decreased with the passage of time, except during transition of the value of the state quantity by said state quantity transition means, and during reset of the value of the state quantity.
