FIR Designer is an educational app for quickly designing, visualizing, and learning about finite impulse response (FIR) filters. Core features include interactive filter specification and real-time frequency/impulse response plots, built-in tutorials and theory explanations for students, and export of filter coefficients and code snippets for MATLAB and Python. Advantages include an intuitive visual interface, instant feedback for iterative learning, and practical export options that bridge classroom concepts and engineering workflows. Ideal for students, instructors, and signal processing engineers looking for a fast, hands-on FIR design tool.

How to use:
1. Download and launch the app, then create an optional account to save projects.
2. Start a new design by choosing filter type, sampling rate, and target specs such as cutoff frequency and filter order.
3. Use the design tool to generate the filter and view real-time frequency and impulse response plots to assess performance.
4. Adjust parameters or use recommended presets and step-by-step tutorials to understand design trade-offs.
5. Export filter coefficients or code for MATLAB/Python, or save/share your project for classroom and lab use.
