Abstract
The object of the present invention is to offer a rate generator which is capable of generating rate signals of arbitrary time intervals over a wide range, from low speeds to high speeds. An N-bit (wherein N is a natural number) counter 1 counts up according to a clock signal 31. An adder 16 pairs off and adds consecutive rate data 32. An adder 17 pairs off and adds rate data 32 which has been shifted by a single step. An adder 18 sequentially adds the addition results of the adder 16. An adder 19 sequentially adds the addition results of the adder 17. A selector 4 alternately selects the addition results of the adder 18 and the addition results of the adder 19. A correspondence circuit 2 receives the output of the counter 1 as a first input and the output of the selector 4 as a second input, and detects matches between the two inputs. A pulse generation circuit 3 is inputted with the output of the correspondence circuit 2 and a clock signal 31, and outputs a rate signal 33.
