Abstract

Przedmiotem zgłoszenia jest układ powiększający stosunek badanego sygnału do szumu własnego czujnika słabych sygnałów magnetycznych zawierający zestaw (ZC) czujników (C1, C2,…Cn) wielkości magnetycznej oraz bloku sumowania sygnałów (S) oraz zestawu filtrów (F1, F2,…Fn), kształtujących pasmo przenoszenia częstotliwości. W układzie tym wyjścia poszczególnych indywidualnych czujników (C1, C2,…Cn), gdzie n jest liczbą naturalną nie mniejszą od dwóch, która zależy od żądanego stopnia powiększenia stosunku sygnału do szumu, połączone są z wejściami filtrów kształtujących pasmo przenoszenia częstotliwości (F1, F2,…Fn), natomiast wyjścia filtrów kształtujących pasmo przenoszenia częstotliwości (F1, F2,…Fn) połączone są z kolejnymi niezależnymi wejściami (S1, S2,…Sn) bloku sumowania (S), na którego wyjściu (SWy) otrzymuje się elektryczny sygnał sterujący o powiększonym stosunku sygnału do szumów własnych indywidualnego czujnika.The subject of the application is a system for increasing the ratio of the tested signal to the self-noise of a weak magnetic signal sensor, comprising a set (ZC) of magnetic quantity sensors (C1, C2,…Cn) and a signal summing block (S) and a set of filters (F1, F2,…Fn) that shape the frequency response band. In this system, the outputs of the individual sensors (C1, C2,…Cn), where n is a natural number not less than two, which depends on the desired degree of increase in the signal-to-noise ratio, are connected to the inputs of the frequency response band-shaping filters (F1, F2,…Fn), while the outputs of the frequency response band-shaping filters (F1, F2,…Fn) are connected to subsequent independent inputs (S1, S2,…Sn) of the summing block (S), the output of which (SWy) receives an electric control signal with an increased signal-to-noise ratio of the individual sensor.
