Question

Direct coupled amplifiers are used to amplify:

• A. Audio frequency signals
• B. Very high frequency signals
• C. Very low frequency signals
• D. RF signals

Hint:

Direct coupling is mostly used for low-frequency signals to avoid the need for capacitive coupling between amplifier stages.

Answer 1

The Correct Option is C

Direct coupled amplifiers are typically used to amplify very low frequency signals. These amplifiers allow the direct connection of stages without capacitive coupling, making them suitable for low-frequency applications.
