#226 In this video I continue looking at crystal and ceramics based piezo-electric filters, by performing some measurements and experiments on a set of filters I've previously built. I take a look at a few stand-alone filter components - like a saw filter and a ceramic resonator but also observe how a crystal ladder filter can be designed and what are some of the things to keep in mind with it.
