kvv77 [185]

Answer:

2.489 dB

Solution:

As per the question:

Power ratio, \frac{P'}{P} = 1.774

The Equivalent of this power ratio in decibel or dB is calculated by taking the log of the power ratio as below:

\frac{P'}{P}_{dB} = 10log_{10}\frac{P'}{P}

\frac{P'}{P}_{dB} = 10log_{10}\times 1.774 = 10\times 0.2489 = 2.489 dB

Thus the value of the power ration in decibel comes out to be 2.489 dB
