Butterworth filter
A low pass filter allows "low" frequencies to pass through a circuit and blocks higher frequencies.
Earth is low pass filter, because it tends to absorbe the amblitude of the high frequency waves.
Gaussian low pass filter is a image smoothing filter which is used to smooth up a digital image...........
low pass or high pass
by combining a low-pass filter with a high-pass filter.[1]
The lowest frequency of an LC low-pass filter is zero, i.e. DC.
A: This is term used to describe a filter that has wide or a big range of frequency available to pass trough. There are others name to describe other ranges of frequency like low pass, hi pass, narrow pass.

A: i am afraid that will take total redesign.
It doesn't.
in second order filter attenuation to the frequencies in stop band is higher then first order filters.
Does not allow high frequencies to pass through the circuit.
