Basic gates

Basic gates screenshot


A demonstration of the basic logic gates. Click the input switches to toggle the corresponding input value between 0 and 1, and watch the resulting behaviour. You can also use shift+click to toggle the input value between the states 0, 1, Z (tri-state, not driven) and X (undefined). The default input values for each are chosen so that the first mouse-click already changes the output value.

The left column includes the non-inverting gates ('positive logic'), namely the one-input buffer, the two-input AND gate, and the two-input OR gate.

The right column shows the inverting gates: inverter, NAND-gate, and NOR gate.
