In the following, which mathematical model represents a linear, time-invariant, lumped and time continuous system (u is the input and y is the output)? y = 2u^2 2.5y + y = u + u y = |u| + u sin (t)y + 2y = u y = 2u

Solution

a) It is parabolic function means non linear function and time invariant system. It is time continuous system.

b) It is a non-linear function and time variant function and it is lumped system and time continuos system

c) It is non linear function. It is time variant and lumped system

d) It is a non linear function and time dependent and not lumped system

e) It is a linear function and continous function. It does not depend on time
