1. What is the decibel of the signal that inputs 100 watt into a repeater and outputs 1,000 watt?s it loss or gain? (10%) 2. Use the following tables to answer the question below.

Sketch the diagram for the following encoding format (30) 4. c) Manchester b) Bipolar-AMI a) NRZ-LExplanation / Answer
1.) Decibel (dB)= 10*log10 (Poutput/Pinput) where Poutput is the output power and Pinput is the input power
After putting the values of power in above equation:
Decibel(dB) = 10 * log10 (1000/100) = 10*log10 (10) = 10 dB
Since decibel value is positive, so it is a gain .
