    I have designed a non inverting amplifier to amplify my signal, together with a bandpass filter to let only a certain group of frequencies to pass. Now my problem is that I am inputting a sine wave and it is outputting another sine wave but I need to know if there are any dc voltages present in the system. I measured an average of the upper antinode and the lower antinode which are 2.31V and -2.39V. Thanks in advance.

    Since you have a bandpass filter in the output, no DC voltage should reach it.

    Have you built the circuit or just simulated it?

    A schematic would be helpful, indicating the points of measurement.
