## Field Documentation

## ◆ energy

q31_t arm_lms_norm_instance_q31::energy

saves previous frame energy.

Definition at line 4198 of file arm_math.h.

## ◆ mu

q31_t arm_lms_norm_instance_q31::mu

step size that controls filter coefficient updates.

Definition at line 4195 of file arm_math.h.

## ◆ numTaps

uint16_t arm_lms_norm_instance_q31::numTaps

number of coefficients in the filter.

Definition at line 4192 of file arm_math.h.

## ◆ pCoeffs

q31_t* arm_lms_norm_instance_q31::pCoeffs

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

Definition at line 4194 of file arm_math.h.

## ◆ postShift

uint8_t arm_lms_norm_instance_q31::postShift

bit shift applied to coefficients.
