Title: Sampling signal processor
Inventor: OSANO YUICHI
IPC: G01R13/20
Filed: 1990-09-07
Abstract: PURPOSE:To reduce waviness of a reproduced signal at a stable part before and after stepwise changed positions by varying a differential coefficient of a sampling point SP in a stable state of an input signal so that it comes closer to a rate of change on the side of the stable state. CONSTITUTION:When an input signal changes stepwise, inclinations m1 to m4 of a polygonal line obtained by connecting respective SP points D-2 to D2 with lines are steep. Therefore when a differential coefficient (t) at the points D-2 to D2 is to be determined, absolute values of the inclinations m1 to m4 are compared with a predetermined threshold value, and cases are classified for example wherein the input signal is stable before the point D0 and the signal suddenly changes subsequently when m1, m2 are smaller than the threshold value and m3, m4 are larger than the threshold value. In order to make a differential coefficient t0 at the point D0 close to a rate of change on the side of the stable side, two SP points D-2, D-1 on the stable side and one SP point D1 on the suddenly changing side are selected, a three-order function passing four points is obtained, and this is used to generate entirely interpolating data between respective points D-2 to D2. Thus even if the input signal changes stepwise, vibration, that is waviness, of reproduced signals corresponding to stable parts before and after the change can be reduced.
