Which of the following is not a static property?(a) repeatability(b) hysteresis(c) frequency response(d) saturationThe question was posed to me in my homework.This key question is from Performance Characteristics of Transducers topic in portion Physiological Transducers of Biomedical Instrumentation

Answer»

The correct answer is (c) frequency response

For explanation I would say: Frequency response is the change of TRANSFER FUNCTION with frequency, both in magnitude and in phase. It is a dynamic property. ABILITY of the sensor to repeat a measurement when put back in the same environment is called repeatability. The region in which the output does not changes with increase in input is called saturation.
