ffilt Scilab Group Scilab Function ffilt
3
ffilt - coefficients of FIR low-pass
8
ft : filter type where ft can take the values
10
"lp" : for low-pass filter
12
"hp" : for high-pass filter
14
"bp" : for band-pass filter
16
"sb" : for stop-band filter
18
n : integer (number of filter samples desired)
20
fl : real (low frequency cut-off)
22
fh : real (high frequency cut-off)
24
x : vector of filter coefficients
27
Get n coefficients of a FIR low-pass, high-pass, band-pass, or stop-band
28
filter. For low and high-pass filters one cut-off frequency must be
29
specified whose value is given in fl. For band-pass and stop-band filters
30
two cut-off frequencies must be specified for which the lower value is in
31
fl and the higher value is in fh
