Electronic Filters Course
This course teaches audio-focused filter design, starting from basic RC filters to advanced active notch and high-pass filters. Students learn to eliminate hum, rumble, and sibilance, select appropriate op-amps and components, and construct reliable, low-noise analog circuits for professional audio signal processing chains. Hands-on skills ensure confident building and deployment of clean-sounding filters.
