| Jun 5, 2020 at 14:01 | comment | added | K.K.McDonald | @Marcus Müller, thank you for your comment, x is the output of the second OP-Amp. The two OP-Amp's up of the circuit are integrator's, I'll refine the shape | |
| Jun 5, 2020 at 13:57 | comment | added | Marcus Müller | If you introduce \$y\$, you save yourself a factor of \$s\$, which might or might not make your problem easier. | |
| Jun 5, 2020 at 13:55 | comment | added | Marcus Müller | where's \$x\$ in your circuit? Do you even need \$x\$? | |
