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?
Assertion: The process of testing the frequency response of amplifier and filter can be done by sweep frequency generator that automatically varies its frequency over a pre-determined range. Reason: The sweep frequency generator should have a ramp generator which applies a linear ramp voltage the input of a voltage tuned oscillator (VTO).
