METHOD FOR TRANSMISSION OF DIGITAL INFORMATION THROUGH ANALOG TELEPHONE LINE

摘要

FIELD: communications, remote control without leased signal line. SUBSTANCE: method involves generation of sine-shaped signal, which correlation is lesser than in speech. This is achieved by modulation of said signal by low-frequency oscillations which period is lesser than interval where spectral and correlation characteristics of speech signal are constant. EFFECT: elimination of relative noise. 2 dwg
