A sample for detecting a pulse 1 cycle time while simultaneously counting the digit counter to 1 at the falling edge of the dial pulse after the first step of performing a sample counter and the dial pulse is recognized as a pulse after the first step. After the second process and the dial pulse is applied after the second process is recognized as a pulse, the digit counter is added by one at the falling edge of the dial pulse, and then the dial pulse is not applied. The third process of detecting that the input level is maintained at the ground level for a predetermined time When the dial pulse is applied within the predetermined time after the third process, the process returns to the third process, and when the input level is the ground level during the predetermined time, the digit counter outputs the digit by the digit counter and the sample counter. And a fourth process of detecting and outputting the pulse high time and the pulse one cycle time.

4. 발명의 중요한 용도4. Important uses of the invention
