Abstract

FIELD: television communication. SUBSTANCE: equipment includes first and second units 1,7 of Walsh transform, first and second units 2,6 of reverse Walsh transform, encoder 3, microtelephone handset 8, telephone set 9, communication line 10. Equipment provides for high degree of security and for decrease of nonlinear distortions of signal uncorrected at reception side and caused by encoding of not components of spectrum with changing amplitudes but of signals of generator of Walsh functions constant in amplitude. EFFECT: enhanced security and reliability of telephone communication. 1 dwg
