Webthe op amp, you need to determine the filter cutoff frequency (fC), also known as the frequency where your filter starts to attenuate the signal. Sometimes, in literature, you will find that this is called the passband frequency. Once this is done, the filter design software program, FilterLab® (available at Webpass signals below the cutoff frequency. In real filters, various trade-offs are made to get optimum performance for a given application. Butterworth filters are termed maximally-flat-magnitude-response filters, optimized for gain flatness in the pass band. The attenuation is –3 dB at the cutoff frequency.
