dfilt.dffirt

Construct a discrete-time, direct form FIR transposed filter object

Syntax

• Hd = dfilt.dffirt(b)
  Hd = dfilt.dffirt
  

Description

Hd = dfilt.dffirt(b) returns a discrete-time, direct form FIR transposed filter object, Hd, with numerator coefficients b.

Hd = dfilt.dffirt returns a default, discrete-time, direct form FIR transposed filter object, Hd, with b=1. This filter passes the input through to the output unchanged.

Examples

Specify a second-order direct form FIR transposed filter structure for a dfilt object, Hd, with the following code:

• b = [0.05 0.9 0.05];
  Hd = dfilt.dffirt(b)
  Hd =
       FilterStructure: 'Direct form FIR transposed'
             Numerator: [0.0500 0.9000 0.0500]
