Electrical Engineering focused.
Four interactive labs for undergraduate circuits, signals and control. Wire a circuit from its elements and read the meters, build a signal and filter it, read a circuit's poles, or close a loop and measure its margins. A circuit built in one lab opens in the others as the same system: an RLC wired in Circuit Elements Lab opens in Circuit Lab, and from there as a filter in Signal Lab and a plant in Control Lab. Every number and every statement on screen is checked by a test against what the page draws.
A series RLC in Circuit Lab is also a biquad. Hand it to Signal Lab and
the same f₀ and Q filter a signal, exactly at the pre-warped
corner. The same network is also a second-order plant. Hand it to Control Lab
and ask how much gain the loop takes before it oscillates. The three labs read one
transfer function three ways, and where a mapping cannot be exact, the panel says
so and gives the reason.
