The system having input x (n) related to output y(n) as y (n) = log |x (n)| is:
A. Nonlinear, causal, stable
B. Linear, noncausal, stable
C. Nonlinear, causal, not stable
D. Linear, noncausal, not stable
Answer:A
The system having input x (n) related to output y(n) as y (n) = log |x (n)| is:
A. Nonlinear, causal, stable B. Linear, noncausal, stable C. Nonlinear, causal, not stable D. Linear, noncausal, not stable
Explanation: As y (n) is the function of x (n) hence it is nonlinear but it is bounded and also depends upon past and present values therefore it is stable and causal respectively.
