If you want to amplify a voltage signal using an op-amp, what mode would you use? How would you control the gain? Draw a circuit diagram that would allow you to amplify the input signal?
By changing the value of resistors we can controo gain
we are using op amp in single ended mode
instead of using two inverting op amp we can use single non inverted op amp also
