Part 1: A signal starts at point X, then travels through point Y to point Z. Between point X and Y, the signal loses 8 dB of strength. At point Y, the signal receives a boost of 10 dB. Then, on the way to point Z, the signal loses another 8 dB. What is the total change in dB between points X and Z?

Part 2: If the signal from part 1 above stats at point X with a power of 100 Watts. What will be the power of the signal at point Z?

Part 3: Assume that the signal needs to arrive at point Z with a minimum power of 50 Watts. What should the initial strength of the signal be increased to?

Answer 1. The total change in dB between points X and Z is 2 dB. Explanation This is because the strength of the signal drops by 8 decibels (dB) between points X and Y, but then surges by 10 decibels (dB) once it reaches point Y. The reason for this
