Description
6 с одинаковыми нижними частотами среза, совиадающими с нижней граничной частотой полосы анализа.6 with the same lower cut-off frequencies, coinciding with the lower boundary frequency of the analysis band.
Возможны различные реализации селектирующего устройства 1 иутем различной комбинации фильтров верхних, нижних частот и иолосовых фильтров с целью обесиечени заданной характеристики.Various implementations of the selection device 1 and different combinations of high and low pass filters and voice filters are possible with the aim of defining a given characteristic.
Работает спектроанализатор следующим образом . Как и обычно, иолоса анализа делитс на N иолос, ширина которых достаточно мала дл того, чтобы по измеренной в ней средней мощности сигнала с достаточной точностью можно было судить о спектральной плотности мощности. Дл измерени средней мощности дл каждой такой полосы измер ют и сравнивают (вычитают) мощность в двух щироких полосах частот, одна из которых равна другой за вычетом рассматриваемой узкой полосы . Сравнение измеренных средних мощностей, оценка измеренных величин с учетом весовых множителей, определ емых шириной соответствующих узких полос частот, и регистраци результатов измерени происход т в блоках 3, 4 и регистраторе 5.The spectrum analyzer works as follows. As usual, the analysis analysis is divided into N andolos, whose width is sufficiently small so that the measured spectral power density can be judged with sufficient accuracy by the average signal power measured in it. To measure the average power for each such band, the power is measured and compared (subtracted) in two wide frequency bands, one of which is equal to the other minus the considered narrow band. Comparison of measured average powers, evaluation of measured values taking into account weighting factors determined by the width of the corresponding narrow frequency bands, and recording of measurement results occur in blocks 3, 4 and recorder 5.
