QUESTION 1 In serial communication, Why do we need I/O synchronization? We need synchronization to measure the time when the microcontroller receives data. A. We need synchronization to measure the time when the microcontroller sends data. B. C. We need synchronization, which is the process of the hardware and software waiting for each other in a manner such that data is properly transmitted. We need synchronization to measure the time when software reads the info and the hardware sends the info. D. QUESTION 2 True Non-intrusiveness is defined as the characteristic or quality of a debugger that allows the software/hardware system to operate normally as if the debugger did not exist True False QUESTION 3 White box testing allows you to control and observe the external workings of a system. False QUESTION 3(a)Discuss the synchronizing torque coefficient and synchronizing power coefficient with expressions. 7 mark (b)A 3-phase generator synchronous with the grid on load at 0.707 power factor lagging, has Xs=5.83 ohm,V=33kv,S=37,5MVA and runs at 1500 rpm to generate 50hz.Calculate the synchronous power coefficient and the synchronizing torque coefficient. 8 mark
