dfilt.dffirt
Discrete-time, direct-form FIR transposed filter
Syntax
Hd = dfilt.dffirt(b)
Hd = dfilt.dffirt
Description
Hd = dfilt.dffirt(b) returns a
discrete-time, direct-form FIR transposed filter, Hd, with numerator
coefficients b.
Hd = dfilt.dffirt returns a default,
discrete-time, direct-form FIR transposed filter, Hd, with
b=1. This filter passes the input through to the output
unchanged.
The resulting filter states column vector is
Examples
Create a direct-form FIR transposed discrete-time filter with coefficients from a 30th order lowpass equiripple design:
b = firpm(30,[0 .1 .2 .5]*2,[1 1 0 0]); Hd = dfilt.dffirt(b)
