PURPOSE:To improve the accuracy comparing with a conventional method with a simplified processor which requires low-power consumption by outputting data values by interpolation and reducing the sampling frequency to the limit. CONSTITUTION:The data at the point of identification are interpolated and outputted by applying digital interpolation circuits 510 and 511 by a time change coefficient FIR filter to a clock reproduction circuit 512. At the same time, the delay time difference between an identification point and a sampling point is removed by interpolation. |
