Summing Amplifier: A summing amplifier is an op-amp configuration that adds multiple input voltages together to produce a single output voltage. Typically implemented using the inverting op-amp setup, each input voltage is connected through a resistor to the inverting input, while the non-inverting input is grounded. The output is proportional to the negative weighted sum of the inputs, depending on the resistor values. It is widely used in audio mixers and signal processing applications. #ampli

This simulation shows how an op-amp summing amplifier takes multiple input signals and combines them into one clean output. You can see three different waveforms applied at the input side—typically a sine wave, a square wave, and a triangle wave. Each input passes through an equal-value resistor, which is important because it makes every signal contribute the same amount to the final result. Inside the circuit, the inverting input of the op-amp sits at what’s called a virtual ground. Even though
