Active Filters - Sallen Key, Multiple Feedback, Higher Order, Butterworth, Bessel, Chebychev

This video is a continuation of our Analog Filters series. As in one of our previous videos, in this video we look at the world of active filters, but this time we dive further into the subject. In this video we learn about higher order active filters and discuss how we can design such filters based on the transfer function. More specifically, we discuss Sallen Key and Multiple Feedback filters and learn about their advantages, disadvantages and function.
