Question: Which of the following configurations can be used to create a summing amplifier?

Options:

Correct Answer: Inverting amplifier

Solution:

A summing amplifier can be created using an inverting amplifier configuration.

Which of the following configurations can be used to create a summing amplifier?

Which of the following configurations can be used to create a summing amplifier?

Step 1: Understand what a summing amplifier does. It adds multiple input signals together.
Step 2: Know that a summing amplifier can be made using an operational amplifier (op-amp).
Step 3: Learn about the inverting amplifier configuration. This is a common way to create a summing amplifier.
Step 4: In the inverting amplifier configuration, multiple input resistors are connected to the inverting input of the op-amp.
Step 5: The output of the op-amp will be a negative sum of the input voltages, which is the desired function of a summing amplifier.
