Question

Check the following equations are linear or non linear by applying the law of homogeneity and Additivity? I. Y(t)= x(t1+t2) II. Y(t)= x(log t)

Answer 1

Answer:

A linear system follows the laws of superposition. This law is necessary and sufficient condition to prove the linearity of the system. Apart from this, the system is a combination of two types of laws −

Law of additivity

Law of homogeneity
