Web17 mei 2015 · It's a two step process: first design your filter (using fir1 or similar commands), then filter the signal with filter or conv. So, nfilt is a vector of filter coefficients, and fnoise is the filtered signal. In Matlab, just type doc fir1 to learn more. – MBaz May 17, 2015 at 20:57 Web21 feb. 2014 · filter doesn't create a filter; it applies a filter to a signal: FILTER One-dimensional digital filter. Y = FILTER (B,A,X) filters the data in vector X with the filter …
