MORE Active RC Filters
#222 In this video I continue looking at the topic of active RC filters by first of all analyzing the All-Pass filter and then looking at some other active circuits that can be used in the building of filter. In particular I look at the negative impedance converter and the general impedance converter. After analyzing what the circuits are supposed to do, I try out some simulations to see how it really works and what sort of circuits can be built around these. Finally I look at a particular filter design tool that give a complete overview, not just of how to chose components but also of the complete behavior including tolerances and op-amp limitations.
