Explanation: For positive time, the system may seem to be causal. For negative time, the output depends on the same time instant, thus making it causal. 10. Comment on the linearity of y[n] = n*x[n]
A. Linear
B. Only additive
C. Not scalable
D. Non linear
Answer:A
Explanation: For positive time, the system may seem to be causal. For negative time, the output depends on the same time instant, thus making it causal. 10. Comment on the linearity of y[n] = n*x[n]
A. Linear B. Only additive C. Not scalable D. Non linear
Explanation: The function obeys the scaling/homogeneity property, but doesn’t obey the additivity property, thus not being linear.
