Project 1: computations about data and signals 1. what is the frequency in hertz of a signal that repeats 80,000 times within one minute? what is its period (the length of one complete cycle)? 2. what is the bandwidth of a signal composed of frequencies from 50hz to 500 hz? 3. a signal starts at points x. as it travels to point y, it loses 8db. at point y, the signal is boosted by 10db. as the signal travels to point z, it loses 7 db. what is the db strength of the signal at point z? 4. in the preceding problem (q3), if the signal started at point x with a strength of 100 watt, what would be the power level of the signal at point z? (a = log10 b  10a = b ) 5. what is the decibel loss of a signal that starts at point a with a strength of 2000 watts and ends at point b with a strength of 400 watts? 6. what would be the power level of a signal that starts at 50 watts and experiences a 10 db loss over a given section of wire?
