Filters can be constructed with much higher order, to achieve higher attenuation in the “stopband” (that is, those frequencies that are supposed to be “stopped” or attenuated) or to achieve particular “passband” shapes (“passband” being those frequencies that the filter is supposed to ...

It is an active filter so the gain can be adjusted if needed The key characteristic of Butterworth is that it has a flat passband and flat stopband. This is the reason it is usually called ‘flat-flat filter’. Now let us discuss the circuit model ofLow Pass Butterworth Filterfor ...
