Realizemdl Support for Polyphase and Farrow Sample Rate Converters
Expanded Demo: Efficient Sample Rate Conversion Between Arbitrary Factors
Input Quantization Added to Models Generated by the Block Method
You can now create Simulink® models of Polyphase and Farrow Sample Rate Converters from the command line using the realizemdl command with mfilt.firsrc and mfilt.farrowsrc.
Multirate Farrow filters can efficiently implement arbitrary (including irrational) rate change factors. You can design Farrow sample rate converters using the new fdesign function fdesign.polysrc.
The expanded efficientsrcdemo.m demonstration now shows you how to design Farrow sample rate converters using the new fdesign.polysrc function.
The fdesign design class, fdesign.halfband, has a new property, type, that you can use to create a lowpass or highpass halfband filter.
Models generated by the block method now include a new input quantization feature.
The new input quantization feature does not work with models generated using previous versions of the software. To restore the previous behavior, open the generated subsystem block, remove the Convert block, and reconnect the remaining block to the subsystem input.
