Summing Amplifier

A summing amplifier is an electronic device that combines multiple electrical signals into a single output. Think of it like a choir where multiple voices (inputs) blend into one harmonious sound (output). It uses an operational amplifier (op-amp) circuit with resistors to weigh each input signal, adding them together to produce a combined voltage. This is useful in audio mixing, sensor data processing, or any situation where multiple signals need to be merged for analysis or further use. The result reflects the total contribution of all the input signals in a single, coherent output.
