numStages

uint16_t numStages

number of stages in the filter.

pkCoeffs

q31_t* pkCoeffs

points to the reflection coefficient array. The array is of length numStages.

pState

q31_t* pState

points to the state variable array. The array is of length numStages+blockSize.

pvCoeffs

q31_t* pvCoeffs

points to the ladder coefficient array. The array is of length numStages+1.
