Which configuration of an OP-AMP is commonly used for modulation?

Step 1: Understand what an OP-AMP is. An OP-AMP (Operational Amplifier) is an electronic device used to amplify voltage signals.
Step 2: Learn about different configurations of OP-AMPs. The two common configurations are inverting and non-inverting amplifiers.
Step 3: Identify the non-inverting amplifier configuration. In this setup, the input signal is applied to the non-inverting terminal of the OP-AMP.
Step 4: Recognize the benefits of the non-inverting configuration. It has a high input impedance, which means it doesn't draw much current from the source.
Step 5: Understand why high input impedance is important for modulation. It allows the OP-AMP to work effectively with various signal sources without affecting them.
Step 6: Conclude that the non-inverting amplifier configuration is commonly used for modulation because of its high input impedance.
