: Hi,
: does anyone knows what a boxcar low-pass filter is and how it works?
: Thanks Raphael
A boxcar filter uses a rectangular window in the frequency domain.
|Hi Everyone, I need simple explanation for the way Boxcar filter works, and if some graphs provided that will be useful. thanks in advance

F_0
frequency--->
Untill F=F_0 it passes all frequencies, while it cuts
signal components above this frequency F_0.
If the filter as a edgy fall-off at F=F_0 it may produce
unwanted effects like a tone at this frequency (e.g.
if you would listen to noise filtered by the boxcar).
Any handbook about (digital or analog) filtering will
describe it in detail.
