WebThe input signal x (t) is varied at fixed value of t (let 1 sec). Then see how the output y (t) is varying at the same value of t. If the relationship between y and x is linear (straight line) and crossing through origin then the system is linear. If you find any time t at which the system is not linear then the system is non-linear.
