Abstract. The analysis of frequency
characteristicû of shunting structures is
carried out on the basis of the theorem about cascade connection of reactive
symmetrical quadripoles. The Interpretation of mathematical passband is given
for reactive symmetrical quadripoles and its change from physical passband is
shown. By the example of the Chebyshev filter it is shown that in physical
passband the complex quadripoles mathematical passband can have stopbands that
brings to the increase of weakening level and reflection coefficient.
