Digital Signal Processing and Filter Design in MATLAB

Digital signal processing is the backbone of modern technology, powering everything from audio engineering to wireless communications. This course guides you through the fundamental concepts of signals and systems, showing you how to bring these mathematical theories to life. You will transition from understanding basic signal theory to confidently implementing, filtering, and analyzing digital signals. Through clear written explanations and practical MATLAB code examples, you will learn to manipulate signals, design digital filters, and analyze spectral data. What you'll learn: Understand foundational signal processing concepts, including sampling, quantization, and the Nyquist theorem; Perform spectral analysis using the Discrete Fourier Transform (DFT) and Fast Fourier Transform (FFT); Design and implement Finite Impulse Response (FIR) and Infinite Impulse Response (IIR) digital filters; Visualize signal waveforms, frequency spectra, and filter responses using MATLAB's robust plotting tools; Apply noise reduction and signal enhancement techniques to real-world data scenarios. The course starts with essential terminology and the mathematical foundations of signals before moving into practical MATLAB implementations. You will explore filter design workflows and spectral analysis through detailed written walkthroughs and code snippets. Designed for beginners, students, and engineers new to DSP, this course requires only a basic understanding of algebra and introductory MATLAB concepts.
