What is a transducer and transponder?

Answer Posted / Varsha Dubey

A transducer is a device that converts energy from one form to another, such as electrical-to-mechanical or mechanical-to-electrical. Examples include microphones (sound to electricity) and sensors (physical phenomenon to electricity). A transponder is a specialized type of transceiver, which transmits information in response to a received signal, often used in radar systems.
