Almost everyone who works with signal processing has Oppenheim and Willsky’s Signals and Systems on their shelf. MIT publishes for free on OpenCourseWare the video lecture series that the book’s author, Alan V. Oppenheim, prepared to go with it, under the name RES.6-007 Signals and Systems.
What’s in it? Linear time-invariant systems, convolution, the Fourier series and transform, filtering, modulation, sampling, and the Laplace and z-transforms. Alongside the videos you can download lecture notes, problem sets and their solutions.
Why we recommend it: The recordings were made many years ago and the picture quality isn’t up to today’s standards. But Oppenheim’s way of building each concept from intuition and only then tying it to the maths is still unmatched. It’s a good next step for anyone who has read our linearity, Fourier and sampling posts and wants to go deeper.
Who is it for? Anyone with basic maths and calculus who wants a solid introduction to signal processing.
