# scipy.signal.kaiserord

`scipy.signal.``kaiserord`(ripple, width)

  Design a Kaiser window to limit ripple and width of transition region.

  Parameters : | ripple : float Positive number specifying maximum ripple in passband (dB) and minimum ripple in stopband. width : float Width of transition region (normalized so that 1 corresponds to pi radians / sample).
  Returns : | numtaps : int The length of the kaiser window. beta : : The beta parameter for the kaiser window.

  `kaiser_beta`, `kaiser_atten`

  Notes

  There are several ways to obtain the Kaiser window:

  - `signal.kaiser(numtaps, beta, sym=0)`
  - `signal.get_window(beta, numtaps)`
  - `signal.get_window(('kaiser', beta), numtaps)`

  The empirical equations discovered by Kaiser are used.
