Show the calculation steps for each of the problems below.
Using Nyquist’ theorem, calculate the channel capacity C of a
signal that has 18 different levels and a frequency of 50,000
Hz.
Using Shannon’s theorem, calculate the data transfer rate given
the following information, signal frequency= 25,000 Hz; signal
power = 5000 watts; noise power = 320 watts.
Using Nyquist’s theorem and given a frequency of 8000 Hz and a
data rate of 90,000 bps, how many signal levels (L)...
