Applied DSP No. 9: The z-Domain and Parametric Filter Design

Applied Digital Signal Processing at Drexel University: In this video, I introduce the z-Domain and the z-Transform, which provide key insights for DSP and an intuitive approach to filter design. == Errata == 2021-11-03: The slide describing the Shift Theorem (around 9:18) has 2 terrible typos... The equations in the z-Domain should have factors of z^-2 and z^-k (not x^-2 and x^-k, as they are in the video). Sorry about that, and my thanks to Tchsurvives for pointing out the error! == I'm teaching the course again this Fall (September 2022), so I really will be posting more in this series in the coming weeks. Now would be a great time to subscribe to my channel, @Youngmoo Kim , for updates. Please leave feedback in the comments and let me know if there are DSP topics you'd like to see in future videos! == Background music by the PolyPhase generative sequencer iPad app. Turns out that while “Rockin’ Robin” is public domain in the US, but not other countries, so there’s still a copyright claim on this video 😡
