matlab-design-digital-filter
Design and validate digital filters in MATLAB. Use when cleaning up noisy signals, removing interference, filtering signals, designing FIR/IIR filters (lowpass/highpass/bandpass/bandstop/notch), or comparing filters in Filter Analyzer.

# Design Digital Filters in MATLAB Design, implement, and validate digital filters using Signal Processing Toolbox and DSP System Toolbox. Choose the right architecture (single-stage vs efficient alternatives), generate correct code, and verify the result with plots and numbers. ## When to Use - Designing lowpass, highpass, bandpass, bandstop, or notch filters - Cleaning up noisy signals or removing interference - Choosing between FIR and IIR filter architectures - Comparing filter designs in Filter Analyzer - Building streaming (real-time) or offline (batch) filtering pipelines - Handling narrow transition bands with multirate or IFIR approaches ## When NOT to Use - Adaptive filtering (LMS, RLS) -- use Signal Processing Toolbox docs directly - Audio-specific processing (equalization, room correction) -- use Audio Toolbox - Image filtering (2D convolution, morphological ops) -- use Image Processing Toolbox - General spectral analysis without filtering intent -- FFT/periodogram docs suffice ## Key Rules - **Read references/INDEX.md** before writing any filter design code. - **Always write to .m files.** Never put multi-line MATLAB code directly in `evaluate_matlab_code`.

What does the matlab-design-digital-filter skill do?
Design and validate digital filters in MATLAB. Use when cleaning up noisy signals, removing interference, filtering signals, designing FIR/IIR filters (lowpass/highpass/bandpass/bandstop/notch), or comparing filters in Filter Analyzer.
How do I install it?
Run `npx skills add matlab/matlab-agentic-toolkit --skill matlab-design-digital-filter --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From matlab/matlab-agentic-toolkit, a repository with 868 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
