Field Documentation

uint8_t M

decimation factor.

uint16_t numTaps

number of coefficients in the filter.

const float32_t* pCoeffs

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

float32_t* pState

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