Potik is a visual block simulator for digital signal processing, RF and radar. You wire blocks — PRBS and tone sources, FIR filters, mixers, channel models, CFAR detectors, beamformers and more — into a graph that runs in a WebAssembly worker right in your browser. Sinks render scopes, spectra, constellations, MSO, range-Doppler and range-angle maps, and polar PPI displays, live as you tune.
The pieces
There are three surfaces, and this site is the front door to all of them:
- The engine — the interactive editor at app.potik.org, where you build and run signal chains.
- Labs — pre-wired signal chains: bundles of blocks already connected into runnable examples, ready to fork and rewire as starting points. Browse them at app.potik.org/labs.
- Embeds — curated and simplified labs served from embed.potik.org, ready to drop into a lesson, textbook or blog post as an interactive demo.
Who it's for
Students meeting the math for the first time, instructors who want a knob to turn in front of a class, and engineers who'd rather prototype a chain in a tab than spin up a licensed toolbox.
