Overview

This repository serves as a lab reference for understanding and implementing core digital signal processing concepts, including convolution, discrete Fourier transform (DFT), finite impulse response (FIR) filtering, and verification of the sampling theorem. Each folder contains code examples, scripts, and individual README files with theoretical explanations to aid understanding of the application and implementation of DSP techniques.

Folder Structure
