Which term describes a device that takes an input analog signal and outputs an analog signal of potentially a different type or range?

• A. Signal Conditioner
• B. Signal Converter
• C. Transmitter
• D. Amplifier

Answer: (B)

Converting an input analog signal into a different analog form or range is the job of a signal converter. It takes the original analog signal and outputs another analog signal, which may be a different type (for example, current to voltage) or scaled to a different range (such as 0–5 V). This explicitly describes changing how the signal appears, not just altering its amplitude or sending it somewhere.

A signal conditioner, while it may adjust levels or filter a signal, is primarily about preparing the signal for measurement without necessarily changing its fundamental type. A transmitter focuses on delivering the signal to another location, often over distance or through a communication medium, rather than changing its form. An amplifier increases the signal’s amplitude but typically keeps the same type and domain of the signal.
