Data Fields | |
uint8_t | L |
uint16_t | phaseLength |
const q31_t * | pCoeffs |
q31_t * | pState |
uint8_t L |
upsample factor.
const q31_t* pCoeffs |
points to the coefficient array. The array is of length L*phaseLength.
uint16_t phaseLength |
length of each polyphase filter component.
q31_t* pState |
