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
