Bandpass Filter

Bandpass Filter is essentially a filter that passes frequencies within a specified range while rejecting frequencies outside of that range. It is used in a variety of applications.


Amplitude-vs-frequency graph

Including a bandpass filter or an lc bandpass filter in your circuit can improve your receiver's sensitivity. Many applications use bandpass filters, including optical communications and audio signal processing. However, for a filter to function properly, its center frequency must be equal to the carrier frequency. This is typically defined by a value known as Q.

Bandpass filters are frequently stacked as high-pass and low-pass filters. This setting reduces the amplitude of the input signal and eliminates unwanted frequencies. A low-pass section can be a standalone filter or stacked on the end of a high-pass filter.

The amplitude response of a bandpass filter is typically plotted on a log-log scale. This graph depicts the output amplitude to input amplitude ratio. This value is usually expressed in decibels and is often graphed on a log-log scale.

In audio signal processing circuits, bandpass filters are commonly used. The ideal filter has a frequency center, bandwidth, and phase.
