Field Documentation

◆ L

uint8_t L

upsample factor.

◆ pCoeffs

const float32_t* pCoeffs

points to the coefficient array. The array is of length L*phaseLength.

◆ phaseLength

uint16_t phaseLength

length of each polyphase filter component.

◆ pState

float32_t* pState

points to the state variable array. The array is of length phaseLength+numTaps-1.
