Solution:

$F_a=1 K_z\\ $

Assume $c_1=0.1 \mathrm{er}$

$\begin{aligned} &F_{-a}=\frac{1}{2 \pi C_1 R_F} \\ &\therefore R_F=\frac{1}{2 \pi \times 0.1 \times 10^{-6} \times 1 \times 10^3} \\ &R_F=1.59 \mathrm{~K} \Omega \end{aligned}\\ $

Calculate $R_1$ and $C_F$

$ \text { Let } \begin{aligned} f_b &=20 f_a \\\\ f_b &=20 \mathrm{kH}_z \\\\ …
