# Information model
## MicroSim spec
- **Recommended sim type:** [[Signal|signal]]-processing
- **Microsimmability score:** 26/100
- **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below.
### Parameters (tunable controls)
- `Frequency` (Hz, input tone frequency)
- `Sample rate` (Hz, samples per second)
- `Cutoff` (Hz, filter corner frequency)
### What animates
An input waveform is sampled and filtered; the time trace and its spectrum redraw as frequency, sample rate, and cutoff change.
### Learning objective
Connect sampling and filtering parameters to the recovered signal and its spectrum.

## Build checklist
- [ ] Claim it: set `status: in-progress` + `lease` + `leased_at`
- [ ] Write the child page explaining the concept (tie it back to systems engineering)
- [ ] Finalize parameter ranges and defaults
- [ ] Implement the p5.js sketch (drawing + control regions)
- [ ] Add caption + the learning objective on the page
- [ ] Set `status: done`
## p5.js sketch
```javascript
// MicroSim: Information model
let controls = {};
function setup() {
// createCanvas(...); create sliders for the parameters above.
}
function draw() {
// background(...); read controls; render signal-processing; respond live.
}
```
