Abstract
A pulse generator circuit includes an adder, a count register which holds the result of addition provided by the adder in order for the addition-result for recursive addition in the adder, a constant register holding a constant required for making said adder continue to perform count-up/count-down operation until a carry/borrow occurs, a parameter register for applying to said adder a correction value for changing, during a normal count-up/count-down operation, the time when carry/borrow occurs, a selector for selecting one of said constant and parameter registers for applying the value held in the selected register to said adder, and a shift register responsive to a carry/borrow occuring in the addition-result from said adder for shifting the content thereof.
