Hi everybody.

I hope you can help me. Ihave a project with operational amplifieres, in this project I need to create a mirror signal(simetrical signal) from this output :

Something like this:

The two requierement are:

  • Only use operational amplifiers, resistences and capacitors
  • The circuit must have two inputs 1 square signal and a triangule signal
I 've trying with many settings , but I have not succeeded.
.
I have this circuit with the original output :

But, that's all.

If someone can help me I will appreciate it.!

Thank you
 
It appears you need to "sum" the two inputs.

The circuit you show has one inverted and one non-inverted, so it will likely produce a difference instead.

Just remove the lower middle opamp (U5) from that, and feed the second signal in through another 4K7 resistor, connected to the negative input of the left hand amp, same as the first signal.

That first opamp, with two (or more) inputs through resistors, forms a "summing" circuit and should do the job.
(Using appropriate parts for low distortion, it's also how simple audio mixers work).
