The MATLAB Discrete Fourier Transform Demo is a VLSI & MATLAB project that combines FFT analysis and Spectrum analyzer, built with Simulink. The project follows a clean, modular design flow where specification, implementation, and verification stay separated, making it easy to test, extend, and present. It showcases practical VLSI and simulation techniques while producing a working, demo-ready design.
Manual and traditional approaches to this design task are slow, error-prone, and difficult to verify. Without a structured VLSI or simulation approach built on Spectrum analyzer and Simulink, designers cannot model, implement, and validate complex circuits or algorithms reliably.
This project applies VLSI and simulation techniques through FFT analysis, orchestrated with Simulink and Spectrum analyzer. The flow is designed for correctness and clarity, with clear implementation, verification, and evaluation stages. It produces consistent, reusable results and can be adapted to related design tasks with minimal changes.
