A afirmação descreve um arranjo experimental composto por um amplificador operacional utilizado como subtrator.
“An ideal operational amplifier acting differentially as a subtractor, has an unitary gain. In this case, the output signal is given by the difference from the voltage signal connected to the negative terminal of the op-amp to the voltage signal connected to the positive one. When the voltage signal connected to the negative terminal is fifty volts (positive) and the voltage signal connected to the positive terminal is one hundred and fifty volts (negative), the output signal is two hundred volts (positive).”
