Question
Which probability distribution is most widely used to
model quantization noise in pulse code modulation ?Solution
In Pulse Code Modulation (PCM), quantization noise arises because the continuous range of amplitudes is mapped into discrete levels. This error is assumed to be equally likely anywhere between ± half the step size of the quantizer. Since every value of quantization error is equally probable within this range, the noise is modeled using a Uniform distribution . This makes analysis simpler and accurately represents the behavior of quantization error in practical systems.
