Abstract

Opracowany sposób redukcji zakłóceń i szumów w układach z dwoma torami sygnałów charakteryzuje to, sygnały wejściowe(x i y) podaje się na sumatory napięć (SX i SY), jak również do sygnałów wejściowych (x i y) dodaje się składowe różnicy tych sygnałów (Uxy), lecz o przeciwnych zwrotach i uzyskuje pary sygnałów pośrednich (x1 i y1) oraz (x1' i y1'), które podawane są na wejścia sumatorów mocy, odpowiedni PC1 i PC2, których napięcia wyjściowe, odpowiednio (p1 i p1') porównuje się ze średnimi wartościami par sygnałów (x1 i y1) oraz (x1' i y1'), czyli odpowiednio wartościami (Sr i Sr'), a różnice tych sygnałów w postaci sygnałów różnicowych, odpowiednio (w1 i w1') podaje się na wzmacniacze, odpowiednio (W1 i W1') o wzmocnieniu (kw, kw'), których sygnały wyjściowe, odpowiednio (w2 i w2') podawane są na sumatory napięć, odpowiednio(SX i SY), na wyjściu których uzyskuje się sygnały wyjściowe (x' i y'). Dla zespołu opracowanych dwóch takich filtrów możliwe jest osiągnięcie tłumienia wszystkich sygnałów wejściowych (x i y) o jednakowych amplitudach o ponad 70 db dla różnic kątowych 25 - 180°, tłumienia o ponad 20 db dla różnic kątowych od +/-15° do +/25° oraz tłumienia o ponad 40 db dla większości sygnałów wejściowych o różnych amplitudach.
