Online simulation of the суммирующий усилитель на операционном усилителе circuit

This circuit outputs the (inverted) sum of the voltages of two input signals. In this case, the first input is a 200 Hz sine wave, and the second input is a 20 Hz square wave. The op-amp tries to keep its - input at the same voltage as the + input (which is at ground). Thus both input signals drive 1 kΩ resistors whose other end is grounded. The current in the third resistor is the sum of the two currents, so the voltage drop must equal the sum of the voltage drops, which is the (negative) sum of the input voltages.

This page is a utility for simulating суммирующий усилитель на операционном усилителе online with specified initial values.

The online circuit simulator allows you to model circuit behavior in real time. You can change circuit parameters, add new elements, and observe their interactions. This is a useful tool for learning and experimenting with electronic circuits.
