dfilt.df2tsos
Discrete-time, second-order section, direct-form II transposed filter
Syntax
Hd = dfilt.df2tsos(s)
Hd = dfilt.df2tsos(b1,a1,b2,a2,...)
Hd = dfilt.df2tsos(...,g)
Hd = dfilt.df2tsos
Description
Hd = dfilt.df2tsos(s)
returns a
discrete-time, second-order section, direct-form II, transposed filter,
Hd
, with coefficients given in the s
matrix.
Hd = dfilt.df2tsos(b1,a1,b2,a2,...)
returns a discrete-time, second-order section, direct-form II, transposed filter,
Hd
, with coefficients for the first section given in the
b1
and a1
vectors, for the second section
given in the b2
and a2
vectors, etc.
Hd = dfilt.df2tsos(...,g)
includes a
gain vector g
. The elements of g
are the gains for
each section. The maximum length of g
is the number of sections plus
one. If g
is not specified, all gains default to one.
Hd = dfilt.df2tsos
returns a
default, discrete-time, second-order section, direct-form II, transposed filter,
Hd
. This filter passes the input through to the output
unchanged.
Note
The leading coefficient of the denominator a(1)
cannot be
0.
The resulting filter states column vector is
