mlib_SignalQuant2_S16_F32 (3MLIB)

Name

mlib_SignalQuant2_S16_F32 - float to 16-bit quantization

Synopsis

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

mlib_status mlib_SignalQuant2_S16_F32(mlib_s16 *dst, 
     const mlib_f32 *src, const mlib_f32 thresh, mlib_s32 length, 
     mlib_s16 offset, mlib_s32 n);

Description

The mlib_SignalQuant2_S16_F32() function quantizes a signal array by using the following equation:

X = x(n)                  n = 0, 1, ...
Z = z(n)                  n = 0, 1, ...
  = offset                for x(n) < t(0)
  = offset + k            for t(k) ≤ x(n) < t(k+1)
  = offset + length - 1   for x(n) ≥ t(length - 1)

Parameters

The function takes the following arguments:

dst

Output signal array

src

Input signal array .

thresh

Array of thresholds.

length

Length of the array of thresholds.

offset

Offset for thresholds.

n

Number of samples in the input signal array.

Return Values

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