Field Documentation

M

uint8_t M

decimation factor.

numTaps

uint16_t numTaps

number of coefficients in the filter.

pCoeffs

const q31_t* pCoeffs

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

pState

q31_t* pState

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