If a signal x(t) is processed through a system to obtain the signal (x(t)2), then the system is said to be:
A. Linear
B. Non-linear
C. Exponential
D. None of the mentioned
Answer:A
If a signal x(t) is processed through a system to obtain the signal (x(t)2), then the system is said to be:
A. Linear B. Non-linear C. Exponential D. None of the mentioned
Explanation: Let the input signal be ‘t’. Then the output signal after passing through the system is y=t2 which is the equation of a parabola. So, the system is non-linear.
