Question 1
a) i. Discuss why the carrier waves are of higher frequency compared to modulating signal and explain in six different ways our inclusion of modulation in communication system.
ii. By a suitable graphical representation sketch signal voltage (V) against period (t) of an FM System at t ranges from 1second to 12 seconds. Taken magnitude of signal voltage to be 10V,
You are required to show work [10 Marks] EV

b) A similar graphical sketch is demanded by a world class telecommunication company to enable analyze their transmission network. You are to appreciate both the signal voltage and the carrier deviation by 55%, to help achieve this feat. All relevant steps are needed. [6 Marks] CR

This question relates to standing waves. A) Does a closed pipe have a higher or lower fundamental frequency than an open pipe of the same length? B) If the length of an open tube is 0.8 m, experimentally find the: fundamental frequency and the frequencies of the third and fifth harmonic. C) We have only addressed the variables of length, wave speed, harmonic number and frequency. These seem to be adequate to fully describe the frequency of a standing wave....

1. Compared to First World countries, developing countries would have _____. a higher life expectancy higher productivity rates lower education levels lower birthrates a higher rate of private investment 2. In many less-developed countries, per capita GDP falls even though real GDP rises, because: output grows at a slower rate than the population. the GDP measures in developing countries are always inaccurate. consumption spending exceeds investment spending. these countries face an acute trade deficit. prices increase faster than an increase...

1- Aliasing can affect DFTs, where higher frequency signals can appear as lower frequency signals due to the use of an N point DFT that has a limit to the highest frequency it can detect. Give one approach when using a DFT to reduce the potential of aliasing. 2-.   When using the standard MATLAB commands, or the design equations, to design an FIR filter why is it a good idea to check if the design meets requirements ? Be specific....
