Extracted text: 1. The electric voltage, V(t) = 150 + 75 sin(20nt) [mV], is going to be observed on the oscilloscope. The oscilloscope display has 10 vertical blocks and 10 horizontal blocks. The oscilloscope parameter is DC-coupling and the vertical position is 0. The choice of volt/div parameter is 10, 25, 50, 100, and 200 [mV/div]. Choose the optimum value for volt/div parameter! Give your reason. (optimum = the signal isn't too big until it is out of the display and also the signal isn't too small to see) a. b. The voltage signal is going to be observed in 5 periods. Calculate the time/div parameter. Based on the initial parameters and the parameters selected in Question a) and b), sketch the voltage signal displayed on the oscilloscope! If the coupling is changed to AC coupling, calculate the average and RMS value of V(t)! с. d.
