The output of an inverter is the complement (opposite) of the input. When the input to an inverter is high (1) the output is low (0); and when the input is low, the output is high. In Boolean Algebra the inverter operation is shown by placing a bar over the variable.
The waveform on the output of an inverter would look like the exact opposite of the waveform on the input. The inverter is also often called a NOT gate.
