Answer and Explanation:

The criteria defined for the instruments that changes rapidly with time, ae called dynamic characteristics. These characteristics are namely

1. Speed of response

2. Fidelity

3. Dynamic error

4. Measuring lag

Speed of response

It is the speed with which a measurement system responds to changes in the measured quantity.

Fidelity

It is the degree to which a measurement system indicates changes in the measured quantity without dynamic error.

Dynamic error

It 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. It is also known as measurement error.

Measuring lag

It is the delay in the response of a measurement system to changes in the measured quantity. It is divided into two as follows.
