Question

A network is said to be linear if and only if

Answer 1

The answer is homogeneity and additivity.

A network is said to be linear if and only if it obeys the basic tests of homogeneity and additivity.

According to the principle of homogeneity, the output function increases in direct proportion to the strength of the simple input applied to the system.

According to the additivity principle, if there is more than one input signal, the output signal will be the same as the sum of the output signals corresponding to the input signals.
