ffilt - coefficients of FIR low-pass
Calling Sequence
- [x]=ffilt(ft,n,fl,fh)
Parameters
-
ft: filter type where ft can take the values
-
"lp" : for low-pass filter
-
"hp" : for high-pass filter
-
"bp" : for band-pass filter
-
"sb" : for stop-band filter
-
n: integer (number of filter samples desired)
-
fl: real (low frequency cut-off)
-
fh: real (high frequency cut-off)
-
x: vector of filter coefficients
Description
Get n coefficients of a FIR low-pass,
high-pass, band-pass, or stop-band filter.
For low and high-pass filters one cut-off
frequency must be specified whose value is
given in fl. For band-pass and stop-band
filters two cut-off frequencies must be
specified for which the lower value is in
fl and the higher value is in fh
