• The ladder structure without mutual inductance is often desirable in the design of filters. Several famous conditions have been provided by T.Fujisawa, H.Watanabe and T.Nishi a long time ago. This paper discusses two special cases of bandpass ladders and provides realizability theorems for them. The bandpass ladders in concern are composed of two basic resonant sections (which we call Sections A and B, as shown in Figs.1(a) and 1(b))which are connected alternately. The prescribed resonant frequency of each Section A is identical (denoted as ω_A).For the first case (the resonant frequency of every Section B (denoted as ω_<B_i>)is larger than ω_A),we give a necessary and sufficient condition (Theorem 1)and for the second case (the case of only two finite attenuation poles, with WA between ω_<B_1>and ω_<B_2>)we give a sufficient condition (Theorem 2).[figure]
