WAVEFORM PROCESSING DEVICE OF NEURAL NETWORK AND ITS DESIGN METHOD

摘要

PURPOSE:To eliminate plural signal degradation factors in a recording/ reproducing system or a transmission system by switching a fixed weight in accordance with the detection value of an auxiliary detection means. CONSTITUTION:The output of a tilt sensor LC which detects the angle formed by the optical axis of the laser beam thrown to an optical disk 103 and the surface of the disk is inputted to a buffer 111, and the output of the buffer 111 is digitized by an A/D converter 112. The digitized extent of tilt is inputted to a controller 113, and data of a ROM 114 is designated by the controller 113, that is, a fixed weight corresponding to the extent of tilt is selected, and the value (fixed weight) of resistances Rji and Rj (R11, R21, R31, R41, R51, R12, R22, R32, R42, R52, R13, R23, R33, R43, R53, and R1 to R3) of a waveform processor WE is set.
