a.As a telecommunication student in this noble institution, Ait to be précised, it is said to be a fact that modulation is seen to be a scheme that ensure signals are made to transverse far with strength and also as process needed to achieve network set up. Use the knowledge acquired in the scheme to put up a modulation plan using any channel of your choice. CDMA or FDM can be used. CR [12 Marks]
b..i. In line with a given bandwidth system, expand on what inform the application of a multi-symbol encoding scheme (which employ far more than 2 symbols)?
ii. Considering FSK transmission where individual symbols are represented by vertical lines: Construct the corresponding binary transmission (voltage pulses), supposing that the higher frequency represents a 1-bit, and determine the bit rate of the system.

a. In a communication system it was agreed to transmit a digital waveform of using time averaging. As a Telecom operation manager you are to analyze and
i. determine the average normalize power.
ii. Recall the above using the summation of spectral coefficients.
iii. Give your opinion about the two solutions.
b. At one of the executive forum of heads of department in the telecom industries it came out that signals are difficult to match each other to bring about quality in the signal after transmission, therefore it rest on you as transmission engineer to put out a discussion to educate the executives on this system and the way forward. Buttress your submission with a mathematical expression and properties with their meaning.
c. Intersymbol interference (ISI) is one of hitches in telecommunication network which has over the years affected the intelligence of signal quality. You are required to employ the services an eye pattern to mitigate this effect.
