MULTIFREQUENCY DELTA-MODULATED SIGNAL RECEIVER Russian patent published in 1997 - IPC

Abstract RU 2090981 C1

FIELD: digital signal processing for electrical communications including telephone communications, to receive multifrequency codes converted into digital form by means of delta modulation. SUBSTANCE: coupling is introduced between OR gate output and one of address inputs of storage unit and count enable input of each correlator is connected to combined count enable inputs of respective reversing and control counters. EFFECT: improved performance efficiency; simplified design attained due to using correlators dispensing with EXCLUSIVE OR gates. 5 dwg, 1 tbl
