You'll get into the nitty-gritty of breaking down complex signals into simpler components. The course covers Fourier series, transforms, and their applications in signal processing. You'll also explore wavelets, which are like mathematical zoom lenses for analyzing signals at different scales. Expect to tackle topics like sampling theory, filter design, and signal compression.
It's not a walk in the park, but it's not impossible either. The math can get pretty abstract, and wrapping your head around concepts like frequency domain might make your brain hurt at first. But once things click, it's actually pretty cool. The toughest part is usually the heavy math involved, so if you're solid with calculus and linear algebra, you'll have a leg up.
