Design an analog computer circuit to solve the differential equation: V0 = 10VS + 2 ∫ VS dt Where VS=input and V0= output.can anyone suggest me the circuit diagram for hardware implementation. as i am not clear about the opamp pin connectivity and the value of the components to be used. if anyone can please. thankyou!

Since this is homework, you will need to show us your best attempt at doing the work before we can help.
It sounds like you have no idea on what to do.

Start at your most basic level :

V0 = 10VS + 2 ∫ VS dt

So if I look at that equation, start with the first term, I need something that scales VS with 10,
in the analog world thats a multiplier or gain (G).

Then I have to take the second term, more G needed, and an integrator, and then a summer
to add first and second term together.

So how do you you make those elements out of OpAmps ?

thankyou sir/mam! but i have done the mathematical modeling. implemented on multisim(online stimulator) but the output is not correct when implemented on hardware. its not yet taught in course.

not discussed in course yet. i have issue with the output and i can't point were i am wrong.

Repeating @crutschow from post #2:
Show us what you've got. An annotated circuit diagram with component values and part numbers.
Show us the expected signals and the real signals you get instead.
