quantizer means..

Answer / saudip sen

An analog signal contains may discrete approximate values
and so during conversion into digital it becomes problematic
as a digital value can only be expressed in the form of 2^n,
where n= a discrete no. Therefore, it becomes essential to
discard these approximate analog values into nearest whole
number. This task is performed by Quantizer. it merely
promotes the signal value to 1 step up if or 1 step down
from the original depending on the status of the signal
available.
Usage:
1.Digital modulation/demodulation ( eg. PCM )

Answer / allanki sanyasi rao

normally during conversion process of analog to digital we
use this quantization process. first of analog signal is
given to band limited filter to band limit the signal to a
particular frequency. then it is given to sampler to
convert that to discrete signal. the sampled signal is
continuous in amplitude and discrete in time. now this
signal is given to quantizer. which approximates all the
sampled values to the nearest quantized values. the no. of
quantized values are M=2^n where n is the no. of bits used
for coding. with n=3 the no. of quantized levels are 8.
with n=4 the no. of quantized levels are 16.with the
increase in no. of quantized levels we can decrease the
quantization noise but it increases required bandwidth.
after quantization the quantized signal is given to coder
to code the quantized signal. the output of the coder is
our required PCM.

finally quatizer approximates each sampled value of a
signal to the nearest quantized value.

Answer / santhosh

SAMPLER AND QUANTIZER ARE THE BASIC ELEMENTS IN DIGITAL
COMMUNICATION.(DC)
SAMPLER:DISCRETISATION IN TIME IS KNOWN AS SAMPLING AND THE
DEVICE WHICH PERFORMS THIS ACTIN IS KNOWN AS SAMPLER.

QUANTISER:DISCRETISATION IN AMPLITUDE IS KNOWN AS
QUANTISATION AND THE DEVICE WHICH PERFORMS THIS AACTION IS
KNOWN AS QUANTISER

quantizer means..

Answer / shweta

quantization means to divide the input signal into finite
number of levels. All the samples fallinf in a paricular
intrval are represented by a discret level.

Answer / ajay kumar yadav

The error is called Quantization. Noise. we may thus write.
Q = M − V. here, the input M has zero mean, and the
quantizer assumed to be symmetric.
