The INVERTER

This is sometimes called an inverting gate or NOT gate. The inverter is the simplest logic gate. You can make one (not a very good one) using one transistor and two resistors. If its input is at 1 its output is at 0. If its input is at 0, its output is at 1. In other words, the output is 1 if the input is NOT 1, hence the name NOT gate.
