PURPOSE:To realize a desired large delayed amount at a high accuracy with a necessarily minimum capacity, by using a memory in the shape of a ring and by obtaining an output by reading out the content of the ring memory at the distance of a delayed amount T from the writing circuit of an input signal. CONSTITUTION:A ring memory 10 has an amplitude which is equal to one bit length and ''1'', when an input signal exists, or ''0'', when on input signal exists, is written in the ring memory 10 by a writing circuit 11 at every clock. When a delayed amount is represented by T, a reading out circuit 12a indicates a ring memory address at a distance of T in the anticlockwise direction from the access address of the writing circuit 11 and reads out the content of the ring memory and uses it as the output signal. Therefore, an optional delayed amount can stably be realized. |
