Quantization Example

Here is an example of a signal being quantized with 3-bit precision using the two different quantization schemes:

Here is the original input. Since we are working with a digital signal, the input is already quantized using 16-bit precision.

Using the full range quantization scheme, we can see the level that each part is quantized at:

We can see the error between the orignal input and the quantized signal:

Using the narrow range quantization scheme, we can see the level that each part is quantized at:

We can see the error between the orignal input and the quantized signal:

Notice that the error is less in the narrow range quantization as opposed to the full range quantization.
