Hello everyone, I would like to find transfer function between input signal \$U_1\$ and output signal \$U_2\$. So, I know how to find the transfer function of each op-amp, for example,

1 transfer function: $$\frac{v_o}{v_i} = -\frac{R_3}{R_1}\frac{1}{1+R_3C_3 s}$$ 2 transfer function: $$\frac{v_o}{v_i} = -\frac{1}{C_4 s R_4}$$ 3 transfer function: $$\frac{v_o}{v_i} = \frac{R_2}{2R}$$

Is that correct way to find $$G(s)=\frac{U_2}{U_1}$$? How can I do it?

Hello everyone, I would like to find transfer function between input signal U1 and output signal U2. So, I know how to find the transfer function of each op-amp, for example,

1 transfer function: vo/vi = -(R3/R1)(1/(1+R3C3s) 2 transfer function: vo/vi = - 1/(C4s*R4) 3 transfer function: vo/vi = R2/2R

Is that correct way to find G(s)=U2/U1 ? How can I do it  ?
