Thus the pass band gain of the filter, AF is therefore given as being: 2. As the value of resistor, R2 divided by resistor, R1 gives a value of one.

Voltage Gain Of an Active High Pass Filter
At high frequencies i.e. when the operating frequency is greater than the cut-off frequency, the voltage gain of the filter is equal to pass band gain. If operating frequency is equal to the cut-off frequency,then the voltage gain of the filter is equal to 0.707 Amax.
How is pass band gain filter calculated?
The centre frequency of the band pass filter which is also termed as 'resonant peak' can be formulated by using the below equation: fc = 1/2π√(LC) Where L = inductance of an inductor whose units are in Henry (H). C = capacitance of a capacitor whose units are in Farad (F).
What is the passband gain?
The passband gain of a filter is simply the amplification factor for signal components that are in the filter's passband.
What is pass band gain of low-pass filter?
Thus, the Active Low Pass Filter has a constant gain AF from 0Hz to the high frequency cut-off point, ƒC. At ƒC the gain is 0.707AF, and after ƒC it decreases at a constant rate as the frequency increases. That is, when the frequency is increased tenfold (one decade), the voltage gain is divided by 10.
