| Apr 10, 2023 at 1:00 | comment | added | periblepsis | @karlkarlsen Ernesto just told you how to see it. You know the gain equation for the (-) input and the way it's tied to the output and ground: \$A=1+\frac{R_2}{R_3}\$. That's going to be multiplied by the high-pass CR filter at the (+) input, where \$\omega_{_0}^2=\frac1{R_1\,C_1}\$ and only depends upon \$R_1\$ and \$C_1\$. Learn to sweep away the details for a moment and see larger pictures which will then help you navigate the math forest, later on. | |

| Apr 9, 2023 at 16:22 | comment | added | karl karlsen | Hi @Andyaka won't they be zero in this case (because its an non-inverting om-amop)? and what is then Z1 and Z2 ? | |
| Apr 9, 2023 at 16:15 | comment | added | Andy aka | You forgot to include C1 and R1 effects. That makes all the difference. | |
