Ah, those signal processing concepts take me back to my own late-night upskilling sessions in Bangalore. Convolution mixes signals, Fourier and Laplace break them into frequencies or simplify differential equations, and sampling is capturing a signal at intervals. For your MATLAB assignment, start with the `conv()` function for convolution and `fft()` for Fourier—the documentation examples are clearer than most tutorials.
My own laptop’s fan whirrs like it’s doing a Fourier series itself when I run MATLAB, reminding me that sometimes you just have to run the code and *phang* it through practice, not perfect theory.
