The correct answer is: C. Digital
A digital transducer is a device that converts a physical quantity into a digital signal. The input signal can be anything that can be measured, such as temperature, pressure, or position. The output signal is a series of discrete numbers that represent the value of the input signal at a given time.
Digital transducers are used in a wide variety of applications, including industrial control, medical diagnostics, and telecommunications. They are often preferred over analog transducers because they are more accurate and reliable.
Analog transducers, on the other hand, convert the input signal into a continuous signal. This type of transducer is less accurate than a digital transducer, but it is often used in applications where speed is more important than accuracy.
Active transducers are transducers that require an external power source to operate. Passive transducers, on the other hand, do not require an external power source.
Pulse transducers are transducers that produce a pulse output signal. This type of transducer is often used in applications where a high-speed response is required.
