Solve linear equations with OP AMP

In this video we have shown that how to solve linear equations with the help of OP-AMP.
For this purpose we need two Inverting OP-AMP.And these two sollution have to be put there.Once the system is assembled,the solltion are obtained in terms of voltage at output.
In practical,high resolution potentiometer are usedto obtain accurate resistance ratios and input voltages.
For more video of OP-AMP comment here.

Thank u, 🙏 easily understood

Walking through the circuit, it really does look like this creates an unstable equilibrium. In other words, this could only function if the output values are absolutely perfect. Otherwise it’s going to feedback and just slam to the rails which is what appears to be doing. What am I not seeing?

Hi, does anyone have a reference like a textbook for such a circuit?

[@anirbandas521]

Thanks a lot bro

What softare you use for editing its cool...

[@sanchitkhare7977]

Please explain this circuit for linear programming problem.

[@pauliexcluded1]

I built this but it just slams to the positive and negative rails. Is there some issue with tr bias currents? What’s going on?

[@uzairmughal4976]

The range of values for x and y are limited to the positive and negative rails. So, for this to work -c1/a1 and the other constant needs to be very small. All in all this circuit does not allow you to vary the ratio of constants too much!

Please make video about integration concept(physically)

[@otamez2262]

Okay

[@pauliexcluded1]

Certainly once you’re in saturation you’re stuck. Help!

[@manojboganadham9071]

What if the ratio of resistances become negative

[@Enigma758]

The resistances are never negative, however the input voltages can be negative.

[@pauliexcluded1]

Yeah this is mathematically flawed I think...
