I see no reason why imquantize() won't work. Please show your code that demonstrates why imquantize() fails. Alternatively you can use mat2gray followed by multiplication, as this demo shows: clc;% Clear the command window. Close all;% Close all figures (except those of imtool.) clear;% Erase all existing variables.

Including uniform quantization coding, non-uniform quantization coding, and A PCM coding rate. Quantizing a complex signal with uniform quantizer in matlab. Analog-to-digital converter (ADC) Outside the realm of signal processing, this category may simply be called rounding or scalar quantization. This MATLAB exercise illustrates the process of uniform quantization of a. Code updates; Read. And other File Exchange content using Add-On Explorer in MATLAB.
