Insertion Loss in Transmission Line Solution

Follow our step by step solution on how to calculate Insertion Loss in Transmission Line?

FIRST Step Consider the formula

I L = 10 \cdot \log 10 (\frac{P t}{P r})

Next Step Substitute values of Variables

∴

I L = 10 \cdot \log 10 (\frac{0.42W}{0.13W})

Next Step Prepare to Evaluate

∴

I L = 10 \cdot \log 10 (\frac{0.42}{0.13})

Next Step Evaluate

∴

I L = 5.09305938091064dB

LAST Step Rounding Answer

∴

I L = 5.0931dB
