(c) If a periodic signal is decomposed into five sine waves with frequencies of 50, 300, 500, 700, and 1800 GHz, what is the bandwidth? Draw the spectrum in periodic and non-periodic form, assuming components have a maximum amplitude of 5,10,1510 and 5V, express this as a function of frequency. Why can't these spectrum be sketch as a function of time?
(a) Surgeons in a hospital want to make use of video conferencing with experts when performing new or unfamiliar surgeries. The networking solution needs to provide very high reliability and speed. Which switching method should be used and why?
(b) Explain with well labeled drawing how analogue and digital data is propagated, give example each.
(c) MTN operating on a frequency of 2.3MHz aim at achieving 15Mbps of data throughput with a successful receiver interpreting an incoming signal to noise (S/N)dB = 12, 18, 25. Calculate the maximum bite rate of each S/N without using calculator explain the tradeoff factor, compare your results with the calculator results, which of this is enough for 4G which aim at achieving 14 Mbps and why?
