Abstract
Sposób pomiaru pojemności linii telekomunikacyjnej charakteryzuje się tym, że sinusoidalny sygnał testowy wytwarzany jest za pomocą syntezy cyfrowej i filtru pasmowo - przepustowego (rekonstrukcyjnego) oraz układ sprzęgający z badanym czwórnikiem, gdzie pomiaru sygnału testowego dokonuje się dwutorowo w identycznych torach pomiarowych, przy czym jeden tor pomiarowy służy do pomiaru generowanego sygnału jako wzorca, natomiast drugi tor służy do pomiaru sygnału wychodzącego z czwórnika, przy czym po pomiarze następuje obliczanie dyskretnych transformat Fouriera zmierzonych sygnałów, następnie otrzymujemy zespolone wartości na podstawie których obliczane jest wzmocnienie badanego czwórnika, a następnie po obliczeniu wzmocnienia, dla otrzymanej wartości uwzględniana jest wartość wzmocnienia wyznaczona podczas procesu kalibracji, przeprowadzanego bezpośrednio przed właściwym pomiarem, następnie znając zmierzone wzmocnienie układu oraz wzór na wzmocnienie czwórnika, wynikający z jego wewnętrznej struktury, wyznaczana jest wartość pojemności.The method of measuring the capacity of a telecommunications line is characterized by the fact that the sinusoidal test signal is generated by means of digital synthesis and a band-pass (reconstructive) filter as well as a coupling system with the tested four-terminal, where the test signal is measured in two ways in identical measuring paths, with one path the measurement is used to measure the generated signal as a standard, while the second path is used to measure the signal coming out of the intersection, whereby the measurement is followed by the calculation of discrete Fourier transforms of the measured signals, then we get the complex values on the basis of which the amplification of the tested intersector is calculated, and then after calculating the gain , the obtained value takes into account the value of gain determined during the calibration process, carried out immediately before the actual measurement, then knowing the measured system gain and the formula for gain ie the four-terminal, resulting from its internal structure, determines the capacity value.
