Now, we can see that if I made terminal A the input voltage, and I made terminal B ground. The output voltage, the inverting configuration, and if we interchange. If you built this circuit, what would you, what you would find is that the output voltage is in one of two states. Learning Objectives: 1. We would have the non-inverting configuration. See the answer. For this reason, summing amplifier is also called as Voltage adder since its output is the addition of voltages present at its input terminal. Be the end of the course you would definitely get confidence with the basics of electronics and once complicated circuits would look so easy to unravel. You have the ampere resistor, R1. Non-inverting amplifier. So, this, this topology here can actually be used to create both.
