There are many different types of filter circuits, with different responses to changing frequency. The frequency response of a filter is generally represented using a Bode plot, and the filter is characterized by its cutoff frequency and rate of frequency rolloff. In all cases, at the cutoff frequency, the filter attenuates the input power by half or 3 dB. So the order of the filter determines the amount of additional attenuation for frequencies higher than the cutoff frequency. WebNote that all three transfer functions have the same denominator and that the numerators have increasing powers of s. That the equations do represent low-pass, high-pass, and bandpass filters can be seen by noting that s is proportional to frequency and by studying the behavior of the equations at such points as ω = 0 and ω = ∞.
