Emphasis optimization device and emphasis optimization methods

摘要

PROBLEM TO BE SOLVED: To provide an optimum setting value of emphasis without being accompanied by troublesome work.;SOLUTION: An emphasis optimization device 1 includes: inverse characteristic calculation means 2 for calculating inverse characteristic of amplitude characteristics from the amplitude characteristics of a transmission line; inverse Fourier transformation means 3 for obtaining an optimum impulse response by subjecting the inverse characteristics of the amplitude characteristics of the transmission line to inverse Fourier transformation; impulse response segmentation means 4 for segmenting the number of taps required for the emphasis to be added to digital signals transmitted on the transmission line from an impulse response; and optimum setting valve calculation means 5 for calculating an optimum setting value by converting the segmented impulse response to a value of the emphasis.;COPYRIGHT: (C)2014,JPO&INPIT
