Prewarp frequency (rad/s)


Prewarp frequency for Tustin method, specified in radians/second.


Settings


Default: 10


Positive scalar value, smaller than the Nyquist frequency before and after resampling. A
value of 0 corresponds to the standard Tustin method without frequency prewarping.


Dependencies


Selecting either



  • Tustin with Prewarping

  • Upsampling when possible, Tustin with Prewarping otherwise


in Sample time rate conversion method on page 16-299 enables this parameter.
