Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFSQNR (Signal-to-Quantization Noise) measures the quality of a quantized signal. It represents the ratio between the signal's power and the power of the quantization error introduced during the quantization process.
Given that S(t) = 3cos (2
SQNR =
fs= sampling frequency.
fm= Modulating frequency.
=
=
Here, option 1 is correct.
