What is the difference between millivolt and volt signal levels, and what are the design implications?

• A. mV signals require high-gain amplification and careful noise management; V-level signals may be easier to route but offer fewer resolution gains.
• B. A device that amplifies high-frequency signals for long-distance transmission.
• C. A component that filters out DC components from a signal.
• D. A sensor that measures temperature changes.

Answer: (A)
