Let h[n] be the impulse response of a discrete-time linear time invariant (LTI) filter. The impulse response is given by
\(h\left[ 0 \right] = \frac{1}{3};\;h\left[ 1 \right] = \frac{1}{3};h\left[ 2 \right] = \frac{1}{3};\) h[n] = 0 for n < 0 and n > 2
Let H(ω) be the discrete-time Fourier transform (DTFT) of h[n]. where ω is the normalized angular frequency in radians. Given that H(ω0) = 0 and 0 < ω0 < π, the value of ω0 (in radians) is equal to ________.
