A low-pass filter is a filter that passes low-frequency signals and attenuates (reduces the amplitude of) signals with frequencies higher than the cutoff frequency. Low-pass filters provide a smoother form of a signal, removing the short-term fluctuations, and leaving the longer-term trend.

A bandpass filter is a filter that can pass a frequency component in a certain frequency range but attenuate other ranges of frequency components to an extremely low level, as opposed to the concept of a bandstop filter. An example of an analog bandpass filter is a resistor-inductor-capacitor circuit (RLC circuit). These filters can also be generated by combining a low pass filter with a high pass filter.
In addition to electronics and signal processing, an example of a bandpass filter application is in the field of atmospheric science. A very common example is the use of a bandpass filter to filter weather data over the last 3 to 10 days, so that the data Only the cyclone that is disturbed is retained in the domain.
Between the lower shear frequency f1 and the higher shear frequency f2 is the resonant frequency, where the gain of the filter is the largest, and the bandwidth of the filter is the difference between f2 and f1.
