Algorithm Definition for the Mid-Tread Quantizer

The mid-tread quantizer uses the following equation to quantize the input signal.

$y=\left[\frac{u}{\mathrm{\Delta}}\right]*\mathrm{\Delta}$

where

*y*is the output signal*u*is the input signal- $\mathrm{\Delta}$ is the quantization interval

Algorithm Definition for the Mid-Riser Quantizer

The mid-riser quantizer uses the following equation to quantize the input signal.

$y=\lceil \frac{u}{\mathrm{\Delta}}-0.5\rceil *\mathrm{\Delta}$

where

*y*is the output signal*u*is the input signal- $\mathrm{\Delta}$ is the quantization interval

**Default: **Mid-tread

Output signal.

This output can return a double-precision, floating-point number or an array of double-precision, floating-point numbers.
