The output SNR can be made independent of input signal level by using
A. Uniform quantizer
B. Non uniform quantizer
C. Both of the mentioned
D. None of the mentioned
Answer:A
The output SNR can be made independent of input signal level by using
A. Uniform quantizer B. Non uniform quantizer C. Both of the mentioned D. None of the mentioned
Explanation: The weak signal experiences poorer SNR compared to high level signals. So if non uniform quantizer like logarithmic compressor is used the SNR ratio can be made independent of input signal level.
