Abstract :
In this paper, we discuss the design of bandpass circulator-tree wave digital filters derived from analog lowpass filters using the geometrical symmetric transformation. These structures are an interesting alternative to lattice WDFs showing a high modularity and posses the same properties as other WDF structures.
