Extracted text: You work as a technical engineer in a company that designs and installs 4G and LTE [wireless cellu networks] solutions for mobile networks like Zain, Orange and Umniah. Your role includes design and optimizing new communications solutions, which requires a good knowledge in sinusoidal sign and their properties. Throughout a new project, your manager has requested your feedback on following cases. Task 1: An alternating current in a 4G signal transmitter is expressed as 1 = 5 sin(120nt + 0.52), I in mA, t in s Find: A. The amplitude, period, frequency and phase shift (phase at time = 0, in degrees) of I B. The value of the current I at: i. t = 0 ii. t = 1/60 What do you notice about your results? C. If the phase of the current I is 1 radians, what is the time at this instance. D. Use MATLAB to plot I for 1 complete period ONLY. E. On the graph, show the point at which the phase of the current I is 1 radian. F. Showing your calculations, find the time at which the current is maximum and positive [hi function is maximum when the angle is t/2 radians, or you can derive and equate to zero!]. iii. t = 1/30 iv. t = 1/15 M .n G. From your plot, find the time, t, yhen current, I is maximum.
