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.
