Web15 apr. 2014 · A low-pass filter is meant to allow low frequencies to pass, but to stop high frequencies. Theoretically, the ideal (i.e., perfect) low-pass filter is the sinc filter. The sinc function ( normalized, hence the π ’s, as is customary in signal processing), is defined as s i n c ( x) = sin ( π x) π x. WebConvolving an input signal with this filter kernel provides a perfect low-pass filter. The problem is, the sinc function continues to both negative and positive infinity without dropping to zero amplitude. While this infinite length is not a problem for mathematics, it is a show stopper for computers.
