## What do you learn in Advanced Signal Processing

Advanced Signal Processing digs into complex signal analysis techniques and their applications. You'll tackle Fourier and wavelet transforms, adaptive filtering, spectral estimation, and statistical signal processing. The course covers digital filter design, multirate systems, and signal compression methods. You'll also explore modern applications like image and speech processing, radar, and communications systems.

## Is Advanced Signal Processing hard?

Advanced Signal Processing can be pretty challenging, not gonna lie. It builds on basic signal processing concepts and throws in a lot of heavy math. The theory can get pretty abstract, and applying it to real-world problems isn't always straightforward. That said, if you've got a solid foundation in signals and systems, and you're comfortable with linear algebra and probability, you can definitely handle it with some effort.
