Instance structure for the Q31 LMS filter.
| Data Fields | |
| uint16_t | numTaps | 
| q31_t * | pState | 
| q31_t * | pCoeffs | 
| q31_t | mu | 
| uint32_t | postShift | 
| q31_t mu | 
step size that controls filter coefficient updates.
| uint16_t numTaps | 
number of coefficients in the filter.
| q31_t* pCoeffs | 
points to the coefficient array. The array is of length numTaps.
| uint32_t postShift | 
bit shift applied to coefficients.
| q31_t* pState | 
points to the state variable array. The array is of length numTaps+blockSize-1.
