The rise time is the time required for the required for the

The rise time is the time required for the required for the system to settle within a certain percentage of the input amplitude. The state variable method (state space representation) can be used to determine the present and future state of a system using inputs and system using inputs and system equations. A stable system is only sage to operate with a given range of values. Select from the expressions below the one that best describes statements (A) to (C) (1) Expression (B) only is correct. Expressions (A) and (C) only are correct. Expression (C) only is correct. Expression (A) only is correct. Expressions (B) and (C) only are correct.

Solution

>> As, the rise time is the time required for the system to settle within 99.9 % of the input amplitude ...(in case of Tmperture distribution)

So, Statement A is correct

>> Statement is wrong, as it does not tell about both past and future

>> Astable system means it is safe to operate under a specific range .....So, Statement C is correct
