Document Type and Number:
Japanese Patent JP2592449
Kind Code:
B2
Abstract:
A line equalizer for eliminating a precursor interference component and postcursor interference components from a pulse signal inputted from a transmission line. A precursor equalizer takes a sum of a signal derived from the input pulse signal retarded by a fundamental period and a signal derived from the input pulse signal multiplied by a coefficient a. A decision circuit decides the threshold level of an output pulse signal from the precursor equalizer to output a predetermined signal. A controller controls the coefficient a of the precursor equalizer on the basis of the signal from the decision circuit, etc.
