Data Fields | |
int8_t | numStages |
q15_t * | pState |
const q15_t * | pCoeffs |
int8_t | postShift |
int8_t numStages |
number of 2nd order stages in the filter. Overall order is 2*numStages.
const q15_t* pCoeffs |
Points to the array of coefficients. The array is of length 5*numStages.
int8_t postShift |
Additional shift, in bits, applied to each output sample.
q15_t* pState |
Points to the array of state coefficients. The array is of length 4*numStages.
