Question

What is the primary characteristic of long loop automatic gain control?

• a) Swift response to rapid signal changes
• b) Lengthy delay in adjusting signal amplitudes
• c) Limited range of gain adjustments
• d) Exclusively used in short-distance communication

Answer 1

The primary characteristic of long loop automatic gain control is lengthy delay in adjusting signal amplitudes. This type of gain control operates over long time scales and is used to maintain a more stable and consistent signal amplitude.

Step-by-step explanation:

The primary characteristic of long loop automatic gain control is lengthy delay in adjusting signal amplitudes. This type of gain control operates over long time scales and is used to maintain a more stable and consistent signal amplitude by adjusting the gain gradually over time. It is commonly employed in communication systems and audio devices to prevent sudden changes in signal amplitude.
