Quantizing

The output from sampling still in the waveform (PAM)

with the respective amplitude. Quantizer will quantize

the signal coming from sampler.

Quantization is the next process by identifying the

binary code to represent the amplitude (voltage) of

the original analog (PAM) signal as per Ts.

The range of the amplitude of the analog signal is

further divided into limited number of level, call

quantization level,

For voice (telephone) the standard bits per sample

(resolution) is 8 bits.

Hence,

where N = no of bits.
