|
|
## Question 1
|
|
Find the energy and average power of $x(n) = e^{j 2\pi n / 3}$
|
|
|
|
Energy of x[n]: Infinity
|
|
Power of x[n]: 1.0
|
|
## Question 2
|
|
Is $x(n - \pi)$ a valid discrete signal?
|
|
|
|
No
|
|
## Question 3
|
|
Consider the system $y[n] = S[x[n]] = e^{n+3}\cos(n-5)x[n-4]$. Is the system linear, time-invariant, causal, and BIBO stable?

|
|
|
Superposition: True
|
|
|
