Given the differential equation model of a physical system, determine the time constant of the system:\(40 \frac{dx}{dt}+2x=f(t)\)
For the following First Order System. The value of steady state error is given by
Direction: Question consists of two statements, one labelled as the 'Assertion (A)' and the other as 'Reason (R)'.Examine these two statements carefully and select the answer to this question using the codes given below:Assertion (A): A linear system gives a bounded output if the input is bounded.Reason (R): The roots of the characteristic equation have all negative real parts and the response due to initial conditions decay to zero as time t tends to infinity.
