Question

The minimum input of physical parameter that will create a detectable out change is called __________

(a) threshold

(b) sensitivity

(c) span

(d) precision

This question was addressed to me during a job interview.

My query is from Performance Characteristics of Transducers in chapter Physiological Transducers of Biomedical Instrumentation

Answer 1

Right answer is (b) sensitivity

The explanation: The sensitivity of the sensor is defined as the slope of the output characteristic curve. In simple words The minimum input of physical parameter that will create a detectable out change is called sensitivity. Total operating range of the transducer is called its span.
