ECE4450 L21: Four-Pole Filters with Feedback: OTA-C Examples (Analog Circuits for Music Synthesis)

Support this channel via a special purpose donation to the Georgia Tech Foundation (GTF210000920), earmarked for my work:    • [OLD] Support This Channel via a Special P...   This is a follow-up to the previous lecture on the theory of four-pole filters with feedback:    • ECE4450 L20: Four-Pole Filters with Feedba...   You should also be sure to watch my lecture on the Moog ladder filter, which is another implementation of the four-pole-with-feedback structure:    • ECE4450 L22: Moog Ladder Filters Analyzed ...   I recorded this during the Spring 2021 offering of ECE4450: Analog Circuits for Music Synthesis, but this material will likely be appropriate for future offerings as well.
