has a pole at $z = 0.8$.

3.1 The DFT of the sequence $x[n] = 1, 2, 3, 4$ is: has a pole at $z = 0

$$H(z) = \frac{1}{1 - 0.5z^{-1}}$$

(b) The odd part of the signal $x[n] = \cos(0.5\pi n)$ is $x_o[n] = 0$. has a pole at $z = 0

$$X[k] = \begin{bmatrix} 10 & -2+j2 & -2 & -2-j2 \end{bmatrix}$$ has a pole at $z = 0

The impulse response of the filter is:

6.1 The IIR filter with a transfer function:
