Hybrid Filter Banks with Overlapping Passbands

The use of a hybrid bank of filters in radio engineering systems makes it possible to achieve both a wider dynamic range of the receiver and an increase in the frequency band processed at a time. The article discusses a method of constructing an analysis filter bank based on analog band pass filters with overlapping passbands. The proposed construction method makes it possible to significantly simplify the practical implementation and tuning of the filter bank. The paper deals with the complexity of designing a hybrid bank of filters in the decameter wavelength range. A comparison of the traditional method of constructing a hybrid bank of filters with the proposed one is made.
