Abstract  Abstract

FIELD: radio engineering; coding digital broadband signals. SUBSTANCE: perceptive weighing device used for producing perceptively weighted signal in responding to broadband signal has signal emphasis entrance filter synthesis filter calculator and perceptive weighing filter. Emphasis entrance filter has transfer function P(z) = 1-muz-1 where mu is emphasis entrance multiplier whose value may be 0 and 1. Perceptive weighing filter has following transfer function: W(z) = A(z/gamma1)/(1-gamma2Z-1) 0<gamma2<gamma1<=1 where gamma2 and gamma1 are weighing control values. As a result weighing broadband signal in formant region is conceptually separated from varying relative level of spectral components of this broadband signal. EFFECT: enhanced reliability of signal recovery. 49 cl 4 dwg
