Question

The range between the maximum and minimum values is applied to a parameter which can be measured is ___________

(a) repeatability

(b) span

(c) input range

(d) output range

This question was posed to me during an interview.

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

Answer 1

Correct option is (b) span

The best explanation: Input range is the range between the max and min values is applied parameter which can be measured . Ability of the sensor to repeat a measurement when put back in the same environment is called repeatability. The total operating range of the transducer is called span of the transducer.
