Find the discrete-time signal whose DTFT is
H(\Omega)=\begin{cases}
1 & \text{if}~|\Omega|\lt{\pi\over2}\\
0 & \text{if}~{\pi\over2}\lt|\Omega|\lt{3\pi\over2}
\end{cases}
and H(\Omega) is periodic in \Omega with period 2\pi.
Enter an expression for h[0]:
h[0] =~
Enter an expression for h[n], n\neq 0:
h[n]\big|_{n\ne0} =~
Assume that H(\Omega) defined above represents the frequency response of a discrete-time system. Determine the response y[n] when the input x[n] is given by
x[n] = \begin{cases}
1 & \text{if}~n=0\\
0 & \text{if}~n=1~\text{or}~n=2
\end{cases}
and x[n] is periodic in n with period 3.
Enter the values of y[n] for -1\le y\le 4 as a list:
[y[-1],y[0],y[1],y[2],y[3],y[4]] =~
