Questions & Step-by-Step Solutions

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.
