In my previous article on common op-amp circuits, I mentioned that operational amplifiers were used for analog computing, where analog circuits simulated the behavior of complex systems. That article ...

I recall excitedly listening to one of my early tech mentors explain the concept of analog computing: “You can easily use op amps to sum and scale any signals, do calculus, or any math you can think ...
