#251 In this video I look at a low pass type of filter which operates on the limit between lumped element and distributed element behavior. Its commonly built from transmission line elements of different impedances but at low frequency it takes advantage of the lines LC behavior. Regardless, its quite an interesting build which can be practically executed either as a PCB structure or as a physicals coaxial structure.
