Suppose a telecommunication company’s booster is emitting a signal of 0.45W, which is being passed through 10 devices. It has been observed that 7 of these devices are encountering noise of 3 microwatts whereas the other 3 devices are encountering noise of 2 microwatts. Considering this information, you are required to calculate the overall Signal to Noise Ratio (SNR) and SNRdB by writing all necessary formulas and calculation steps.
Solution:
Here we have,
Average signal power =0.45w
Average signal power=0.45x106microwatts=450000 microwatts
Average Noise power for 7 Devices =3 microwatts = 21 microwatts
Average Noise power for 3 Devices= 2 microwatts=6 microwatts
Total Average Noise power=2.7 microwatts
- Signal to Noise Ration (SNR)=?
- SNRdB=?
(i)The formula for a signal to Noise Ration (SNR) is:
Signal to Noise
Ratio (SNR)=Average Signal power / Average signal power
Signal to Noise Ratio (SNR)= 450000 / 2.7
Signal to Noise Ratio (SNR)=166,666,6 mifcrowatts
ii)
The formula for SNR=is:
SNRdB= 10 log10SNR
SNRDb = 10 log10166666.67
SNRdB= log10(5.22)
SNRDb=52.2 approx.
