Title:
EQUALIZATION DEVICE, EQUALIZATION METHOD, AND SIGNALING DEVICE
Document Type and Number:
Japanese Patent JP2018110363
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an equalization device, an equalization method, and a signaling device capable of suppressing degradation in bit error rate.SOLUTION: A linear equalizer has: a low-frequency zero point circuit 810 that has a zero point in a low-frequency band in frequency characteristics before equalization of communication medium; a high-frequency zero point circuit 808 that has a zero point in a high-frequency band in the frequency characteristics before equalization of the communication medium; and an intermediate-frequency zero point circuit 809 that has a zero point in an intermediate frequency band existing between the low-frequency band and the high-frequency band and where an inclination of a waveform in the frequency characteristics before equalization of the communication medium is changed. A signal transmitted through the communication medium is equalized so as to suppress a change amount of the inclination of the waveform in the frequency characteristics after equalization.SELECTED DRAWING: Figure 8
