What is non uniform quantization and the associated drawbacks?

What is the disadvantage of uniform quantization over the non-uniform quantization? SNR decreases with decrease in input power level at the uniform quantizer but non-uniform quantization maintains a constant SNR for wide range of input power levels.

What are the advantages of non uniform quantization?

Advantages of non-uniform Quantization

SNR of the non-uniform quantization is higher than the uniform quantization. It is because the non-uniform level requires large number of quantized levels are more expanded. The quantizer noise of the non-uniform quantization is low than the uniform quantization.

Why non uniform quantization is better than uniform quantization?

Another important difference between uniform and nonuniform quantization is that, in the uniform quantization, some amount of quantization error can happen, but nonuniform quantization reduces the quantization error. Communication systems send signals from the transmitter to the receiver.

Which is better uniform or non uniform quantization?

The nonuniform quantization strategy for compressing neural networks usually achieves better performance than its counterpart, i.e., uniform strategy, due to its superior representational capacity.
