1. An inverting
amplifier - Leg two is the input and the output is always
reversed or inverted. 2. A Non-inverting amplifier - Leg three is the input and the output is not reversed. |

Opposite is a diagram of an INVERTING AMPLIFIER.
This means that if the voltage going into the 741 chip is positive, it
is negative when it comes out of the 741. In other words it reverses
polarity (inverts polarity). |

|
The polarity of a signal is
reversed at the output, pin six. |
A signal applied keeps its
polarity at the output, pin six. |
