ADJUSTMENT METHOD OF DIGITAL PHASE CORRECTOR

摘要

FIELD: electricity. ^ SUBSTANCE: trial signal is supplied to input of communication line; discrete signal on the basis of which left circuit matrix is formed is obtained at the output of communication channel; output signal of phase corrector is determined; increments of output signal of phase corrector are determined as differences of readings of output signal of phase corrector and readings of trial input signal; discrete spectrum of the first column of left circuit matrix is determined; discrete spectrum of increments of output signal of phase corrector is determined; discrete spectrum of increments of coefficients of phase corrector is determined with division of discrete spectrum of increments of output signal of phase corrector by discrete spectrum of the first column of left circuit matrix of communication channel; increments of coefficients of phase corrector is determined with return discrete conversion of spectrum of increments of phase corrector coefficients; new coefficients of phase corrector are determined as difference of values of available coefficients and values of increments of coefficients. ^ EFFECT: shortening the time and improving the accuracy of adjustment of phase corrector.
