Clearly show your work.(note: frequency is the number of cycles in one second and T 1/f, where T is period and fis frequency in Hz). 2. What is the bandwidth of a signal composed of frequencies from 50 Hz to 500 Hz? If a bandwidth of a signal is 10iz and its maximum is 1200 Hz, what is the minimum frequency of the signal. Clearly show your work. (Note: Bandwigth Maximum frequency-minimum frequency 3.If quadrature amplitude modulation is used to transmit a signal with a baud rate of 8000, what is the corresponding bit rate? Clearly show your work. (Note: 2bits/modulation level in Phase Shift Keying) # of modulation levels also study the example mentioned 3. A signal starts at point X. As it travels to point Y, it loses 8 dB. At point Y, the signal is boosted by 10 bB. As the signal travels to point Z, it loses 7 dB. What is the dB strength of the signal at point Z? If the signal started at point X with a strength of 100 watts, what would be the power level of the signal at point 2? 4. Twenty-four voice signals are to be transmitted over a single high-speed telephone line. What is the bandwidth required (in bps) if the standard analog to digital sampling rate is used and each sample is converted into an 8 bit value? Assume the maximum voice frequency is 4000 Hz.
