Question 141Electricity & Electronics - 1st Asst/Chief

The correct answer is C) analog electrical signal. The "TRANSDUCER" block in the illustrated signal processing flow path represents a device designed to sense and measure a physical parameter and convert it into a proportional analog electrical signal. Transducers are commonly used to convert physical quantities like pressure, temperature, or flow rate into corresponding electrical signals that can be further processed and analyzed. The other options are incorrect because: A) a digital electrical signal is a discrete, numerical representation of the physical parameter, not a proportional analog signal; B) an electromechanical force is the output of the transducer, not the type of signal it produces; and D) a pneumatic signal is a pressure-based signal, not an electrical one.
