Field Documentation

◆ M

uint8_t M

decimation factor.

◆ numTaps

uint16_t numTaps

number of coefficients in the filter.

◆ pCoeffs

const q15_t* pCoeffs

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

◆ pState

q15_t* pState

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