Field Documentation

mu

q31_t mu

step size that controls filter coefficient updates.

numTaps

uint16_t numTaps

number of coefficients in the filter.

pCoeffs

q31_t* pCoeffs

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

postShift

uint32_t postShift

bit shift applied to coefficients.

pState

q31_t* pState

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