Nodanalys i o ger: - $\frac{U_{in}}{R_1} - \frac{V}{R_2} = 0 \Rightarrow V = -\frac{R_2}{R_1} U_{in}$
Nodanalys i V: $\frac{V}{R_2} + \frac{V}{R_4 + \frac{1}{j\omega_c}} + \frac{V - U_{ut}}{R_3} = 0$

\left(\frac{1}{R_2} + \frac{1}{R_3}\right) V + \frac{j\omega_c}{1 + j\omega R_4 c} V = \frac{1}{R_3} U_{ut} \Rightarrow U_{ut} = \left(1 + \frac{R_3}{R_2} + \frac{j\omega R_3 c}{1 + j\omega R_4 c}\right) V U_{ut} = -\frac{R_2}{R_1} U_{in} \left( \frac{R_2 (1 + j\omega R_4 c) + R_3 (1 + j\omega R_4 c) + j\omega R_2 R_3 c}{R_2 (1 + j\omega R_4 c)} \right) \Rightarrow U_{ut} = -\frac{1}{R_1} U_{in} \left( \frac{R_2 + j\omega R_2 R_4 c + R_3 + j\omega R_3 R_4 c + j\omega R_2 R_3 c}{1 + j\omega R_4 c} \right) A_N = \frac{U_{ut}}{U_{in}} = -\frac{1}{R_1} \left( \frac{R_2 + R_3 + j\omega (R_2 R_4 + R_3 R_4 + R_2 R_3) c}{1 + j\omega R_4 c} \right) \Rightarrow A_N = -\frac{R_2 + R_3}{R_1} \left( \frac{1 + j\omega \frac{R_2 R_4 + R_3 R_4 + R_2 R_3}{R_2 + R_3} c}{1 + j\omega R_4 c} \right)
