The Nyquist–Shannon theorem says you must sample faster than twice the highest frequency. Sample too slowly and a high frequency masquerades as a low one — aliasing — which is why anti-alias filters guard every ADC. Educational tool.

About this simulation
The full Sampling & Nyquist tool models a Class-D amp with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
