A band – pass filter (also bandpass filter , BPF ) is a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range.

Active Band Pass Filter.
The principal characteristic of a Band Pass Filter or any filter for that matter, is its ability to pass frequencies relatively unattenuated over a specified band or spread of frequencies called the “Pass Band”.
For a low pass filter this pass band starts from 0Hz or DC and continues up to the specified cut- off . There are applications where a particular ban or sprea or frequencies need to be filtered from a wider range of mixed signals. Filter circuits can be designed to accomplish this task by combining the properties of low-pass and high-pass into a single filter. The result is called a band – pass filter. Creating a bandpass filter.
The following circuit is an example of a band pass filter : First we will consider a qualitative analysis of the circuit. Recall that the impedance of the inductor and capacitor are: and. Continue reading “Band pass filter”
