ippStsSamplePhaseErr

In multirate processing, phase selects which polyphase branch or sample position is used. The valid phase range is tied to the sampling factor.

A wrong phase can produce shifted or invalid output even when the input buffer and filter coefficients are otherwise correct.

Check these details

  • Phase is non-negative and less than the sampling factor.
  • State carried between streaming blocks.
  • Any modulo operation used when restoring phase from a previous chunk.
