Consider the following statements for dynamic characteristics of a measurement system: 1. Fidelity is defined as the degree to which a measurement system indicates changes in the measured quantity without any dynamic error. 2. Dynamic error is the difference between the true value of the quantity changing with time and the value indicated by the measurement system if no static error is assumed. 3. Measuring lag is the retardation in the response of a measurement system to changes in the measured quantity. Which of the above statements are correct?
