NAME

       mlib_SignalGaussNoise_S16 - Gaussian noise generation

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_SignalGaussNoise_S16(mlib_s16 *gnoise, void *state,
	    mlib_s32 n);

DESCRIPTION

       The mlib_SignalGaussNoise_S16() function generates one packet of Gaussian noise and updates the internal state.

PARAMETERS

       The function takes the following arguments:

       gnoise	 Generated Gaussian noise array.

       state	 Internal state structure.

       n	 Length of the generated Gaussian wave array in number of samples.

RETURN VALUES

       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.

NAME

       mlib_SignalGaussNoiseInit_S16 - Gaussian noise generation

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_SignalGaussNoiseInit_S16(void **state, mlib_s16 mag, mlib_f32 mean, mlib_f32 stddev, mlib_s16 seed);

DESCRIPTION

       The  mlib_SignalGaussNoiseInit_S16() function allocates memory for an internal state structure and converts the parameters into an internal
       representation.

PARAMETERS

       The function takes the following arguments:

       state	       Internal state structure.

       mag	       Magnitude of the Gaussian noise to be generated, in Q15 format.

       mean	       Mean of the Gaussian noise.

       stddev	       Standard deviation of the Gaussian noise.

       seed	       Seed value for the pseudorandom number generator.

RETURN VALUES

       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
