Passive Filters: Band Pass Circuits

Wideband Filter Only Has Two Different Components : 01/21/02 Electronic Design - Ideas for Design /  Wideband filters with bandwidths in excess of an octave can be created by cascading a high-pass filter and a low-pass filter. In this design idea, nine-pole high-pass and low-pass filters have been constructed using a modified equal-element design.
