Question

_____________ is an instrument having no dynamic error and no time lag of measurement.

(a) Frequency response

(b) Dynamic response

(c) First order response

(d) None of the mentioned

I have been asked this question in an international level competition.

Enquiry is from Intake Air Flow Measurement in portion Engine Electronics of IC Engine

Answer 1

Answer: (d) None of the mentioned

Explanation: The correct answer is typically "Zero-order response", which is an idealized situation where the instrument has no dynamic error and no time lag in measurement. This means the instrument measures changes instantaneously without any delay or error in the measurement, which is ideal for precise and immediate readings.

The options provided, such as frequency response, dynamic response, and first-order response, describe systems that involve some form of delay or time lag in their measurements.
