If a filter has unity gain (i. e. 0 db) in its passband, you know that the frequency at which the output has half the amplitude of the input is known as the cutoff frequency. hence, the gain is −3 db at the cutoff frequency. however, if the maximum gain in the passband is not 0 db, the cutoff frequency is the point where the gain is 3 db lower than the maximum gain. when measuring cutoff frequency from the bode plot, if you notice that the maximum gain is 8 db, then what is the gain at the cutoff frequency?
