#225 In this episode I start looking at piezo-electric based components that can be used in filter circuits. Things like ceramic resonators, quartz crystals and SAW or BAW filter components can all be categorized into a wider class of piezo-electric components. I first look at what are the principles used by such a component and then continue by looking at the equivalent electrical model. Finally I run some basic measurements and also look at how a filter can be built around a crystal type component.
