uint32_t | numStages |
q31_t * | pState |
const q31_t * | pCoeffs |
uint8_t | postShift |
uint32_t numStages |
number of 2nd order stages in the filter. Overall order is 2*numStages.
const q31_t* pCoeffs |
Points to the array of coefficients. The array is of length 5*numStages.
uint8_t postShift |
Additional shift, in bits, applied to each output sample.
q31_t* pState |
Points to the array of state coefficients. The array is of length 4*numStages.
