With some algebraic manipulation (including multiplying the numerator and denominator by s/R), you can find the transfer function T(s) = V R (s)/VS(s) of a high-pass filter:. You have a zero at s = 0 and a pole at s = –1/(RC).You start off the frequency response with a zero with a positive slope of 20 dB/decade, and then the response flattens out starting at 1/(RC).

More### Active Band Pass Filter Circuit Design and Applications

Introduction. A Band Pass Filter is a circuit which allows only particular band of frequencies to pass through it. This Pass band is mainly between the cut-off frequencies and they are f L and f H, where f L is the lower cut-off frequency and f H is higher cut-off frequency.. The centre frequency is denoted by ‘f C ’ and it is also called as resonant frequency or peak frequency.
