Q1.
Q2. When we have a LTI system, the impulse response $ h[n] $ must be real
in order for $ y[n] $ to be real whenever $ x[n] $ is real.
The condition for $ h[n] $ to be real is
$ h[n]=h^{\ast}[n] $
Then, what is the condition of the frequency response $ H(w) $ for $ h[n] $ to be real?
(Hint: Apply DTFT to the above equation)
