Field Documentation

numTaps

uint16_t numTaps

number of filter coefficients in the filter.

pCoeffs

const float32_t* pCoeffs

points to the coefficient array. The array is of length numTaps.

pState

float32_t* pState

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