Extracted text: You work as a technical engineer in a company that designs and installs 4G and LTE (wireless cellular networks solutions for mobile networks like Zain, Orange and Umniah. Your role includes designing and optimizing new communications solutions, which requires a good knowledge in sinusoidal signals and their properties. Throughout a new project, your manager has requested your feedback on the following cases. Task 1: An alternating current in a 4G signal transmitter is expressed as I= 5 sin(120mt + 0.52), I in mA, t in s, Find: A. The amplitude, period, frequency and phase shift (phase at time - 0, in degrees) of B. The value of the current / at: iii. t- 1/30 iv. t- 1/15 i.t-0 ii.t-1/60 What do you notice about your results? C. If the phase of the current / is I radians, what is the time at this instance.
