FIELD: radio engineering; broadband signal communication systems. ^ SUBSTANCE: proposed device is characterized in optimal selection of energy level choice for broadband signal spectrum section where narrow-band noise is being suppressed. Proportion of cross-correlation coefficient of distorted and reference signals, as well as that of noise and signal is proposed to be used as index of noise immunity. Novelty is introduction of START button, RS flip-flop, frequency tuning unit, comparison circuit, first adder, two squarers, second adder, power meter, normalizing unit, converter, gating pulse shaper, pulse generator, selector switch, memory register, division unit, delay line, comparator, and regulator in prior-art device for detecting noise-affected spectrum of signal. ^ EFFECT: enhanced noise immunity in radio reception. ^ 1 cl, 1 dwg |
