NAME

       mlib_SignalWhiteNoise_S16 - white noise generation

SYNOPSIS

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

       mlib_status mlib_SignalWhiteNoise_S16(mlib_s16 *wnoise, void *state, mlib_s32 n);

DESCRIPTION

       The mlib_SignalWhiteNoise_S16() function generates one packet of white noise and updates the internal state.

PARAMETERS

       The function takes the following arguments:

       wnoise	       Generated white noise array.

       state	       Internal state structure.

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

RETURN VALUES

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

NAME

       mlib_SignalWhiteNoiseInit_S16 - white noise generation

SYNOPSIS

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

       mlib_status mlib_SignalWhiteNoiseInit_S16(void **state, mlib_s16 mag, mlib_s16 seed);

DESCRIPTION

       The  mlib_SignalWhiteNoiseInit_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 white noise to be generated, in Q15 format.

       seed	       Seed value for the pseudorandom number generator.

RETURN VALUES

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