Let h[n] be the impulse response of a discrete-time linear time invariant (LTI) filter. The impulse response is given by
h[0]= ; h[1]= ;h[2]= ;and h[n]=0 for n<0 and n>2
Let H(ω)be the discrete-time Fourier system transform (DTFT) of h[n], where ω is the normalized angular frequency in radians. Given that H(ω)=0 and, the value of (in radians) is equal to _______.
