Cavity Filter Basics

#227 In this video I look at another constructive type of filters that moves from the world of lumped elements to the world of distributed elements, what I'm referring to is cavity filters. I look at some of the basic operating principles as well as some constructive types and next time I will be performing some measurements on a set of practical devices.
