Description

Instance structure for the floating-point normalized LMS filter.

Examples

arm_signal_converge_example_f32.c.

Field Documentation

energy

float32_t energy

saves previous frame energy.

mu

float32_t mu

step size that control filter coefficient updates.

numTaps

uint16_t numTaps

number of coefficients in the filter.

pCoeffs

float32_t* pCoeffs

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

pState

float32_t* pState

points to the state variable array. The array is of length numTaps+blockSize-1.

x0

float32_t x0

saves previous input sample.
