Answer:
2.489 dB
Solution:
As per the question:
Power ratio, [tex]\frac{P'}{P} = 1.774[/tex]
The Equivalent of this power ratio in decibel or dB is calculated by taking the log of the power ratio as below:
[tex]\frac{P'}{P}_{dB} = 10log_{10}\frac{P'}{P}[/tex]
[tex]\frac{P'}{P}_{dB} = 10log_{10}\times 1.774 = 10\times 0.2489 = 2.489 dB[/tex]
Thus the value of the power ration in decibel comes out to be 2.489 dB
