All Multirate Filter Structures Support Complex Coefficients
New Multirate Farrow Filter Capable of Sample Rate Conversion
The two classes farrow.fdand farrow.linearfd have been moved into dfilt.farrowfd and dfilt.farrowlinearfd, respectively.
All structures for mfilt multirate filters can use complex coefficients.
A new multirate filter, mfilt.farrowsrc, has been added to mfilts, allowing for Farrow decimators and interpolators, and fractional decimators and fractional interpolators where the resulting interpolation or decimation factor is not an integer.
Updates to structure of User's Guide and Getting started include sections about using filterbuilder and a new chapter about using integers with FIR filters
The farrow.fd and farrow.linearfd functions have been removed. For more information about the removal of these functions, see Functions Being Removed.
Function Being Removed | What Happens When You Run the Function? | Use this Function Instead | Compatibility Considerations |
|---|---|---|---|
farrow.fd | Still runs | dfilt.farrowfd | Farrow filters are now constructed using the dfilt (discrete-time filter) structure. Instead of using farrow.fd, use dfilt.farrowfd. See the reference page for dfilt for more information. |
farrow.linearfd | Still runs | dfilt.farrowlinearfd | As noted above Farrow filters are now created using the dfilt constructor. |
