Questions & Step-by-Step Solutions

What is the primary function of an operational amplifier?
  • Step 1: Understand what an operational amplifier (op-amp) is. It is an electronic device used in circuits.
  • Step 2: Know that the main job of an op-amp is to take a small voltage signal and make it bigger.
  • Step 3: Realize that this process of making the signal bigger is called 'amplification'.
  • Step 4: Remember that op-amps can amplify both AC and DC voltage signals.
