SNR for AM Demodulation Solution

Follow our step by step solution on how to calculate SNR for AM Demodulation?

FIRST Step Consider the formula

SNR am = (\frac{μ^{2} \cdot A sm}{1 + μ^{2} \cdot A sm}) \cdot SNR

Next Step Substitute values of Variables

∴

SNR am = (\frac{{0.36}^{2} \cdot 0.4}{1 + {0.36}^{2} \cdot 0.4}) \cdot 0.602dB

Next Step Prepare to Evaluate

∴

SNR am = (\frac{{0.36}^{2} \cdot 0.4}{1 + {0.36}^{2} \cdot 0.4}) \cdot 0.602

Next Step Evaluate

∴

SNR am = 0.0296696075448737dB

LAST Step Rounding Answer

∴

SNR am = 0.0297dB
