Binary encoding of quantization levels - ScienceDirectELSEVIERPractical Digital Signal Processing
So the last stage in the ADC is the code conversion, which formats the data into a binary numerical representation. The choice of the number of quantization levels determines the dynamic range of a digital PCM system. To a first approximation the dynamic range in dB is the number of digits...
Take all oc of your numbers and quantize them each to be 0 or 1. Now take all of the bits that result and put them together in sequence to form one binary number. Now quantize that binary number down to 0 or 1. We have started with an arbitrary long sequence of numbers and we hav...
However, in case of nonuniform quantization, the step size changes so it will have a minimum amount of error. After completing the quantization, the next step is encoding. It defines each quantization level by a binary code. What is the Difference Between Uniform and Nonuniform Quantization? U...
This leads directly to variable-rate quantization, which has the partition into cells and codebook of levels as before, but now has binary codewords of varying lengths assigned to the cells (alternatively, the levels). Ordinarily, the set of binary codewords is chosen to satisfy the pre?x ...

32x: Binary quantization (1-bit dimensions) 4x: Byte and integer quantization (8-bit dimensions) 2x: FP16 quantization (16-bit dimensions) This method also supports other compression levels such as 16x and 8x that aren’t available with the in-memory mode. To enable di...
Binary code produced by the ADC. Solution: Since the range is from 0 to 5 V and the 3-bit ADC is used, we have xmin=0V,xmax=5V,andm=3bits. (a) Using Eq. (2.35), we get the number of quantization levels as L=2m=23=8. (b) Applying Eq. (2.34) yields Δ=5−08=0.625...
In addition, this technique may be applied to binary trees used in certain prior art vector quantization systems for encoding efficiency. The improved vector quantizer 330 is organized in a tree structure. Instead of a binary tree as used in certain prior art schemes, at the root of the ...
