$$h[n] = 0.5^n u[n]$$

5.1 The FIR filter with a length of 3 and coefficients $b_0 = 1, b_1 = 2, b_2 = 3$ has a transfer function: $$h[n] = 0

$$X[k] = \begin{bmatrix} 10 & -2+j2 & -2 & -2-j2 \end{bmatrix}$$ b_1 = 2

6.1 The IIR filter with a transfer function: $$h[n] = 0

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