Question

The region in which the output does not changes with increase in input is called _________

(a) input range

(b) threshold

(c) offset

(d) saturation

This question was posed to me in an interview.

Origin of the question is Performance Characteristics of Transducers topic in section Physiological Transducers of Biomedical Instrumentation

Answer 1

Correct option is (d) saturation

The explanation: The region in which the output does not changes with increase in input is called saturation. The threshold of the transducer is the smallest change in measurant that will result in a measurable change in the transducer output. Offset is the output that will exist when it should be zero.
