Set the input voltage of the AC network as V(t) = 12sin(2π(125)t) V by using a signal generator and oscilloscope for a circuit. Given R1 = 900Ω and R2 = 1kΩ. The signals of Vin and Vout were displayed on the oscilloscope screen synchronously. If the vertical section and the horizontal section were set to 4 V/div and 1 ms/div, draw the waveforms for both signals (Vin and Vout) displayed with the proper labels. Also, show the calculation for the output voltage, Vout (calculated).
