Three speech signals are TDM multiplexed with a high-quality music signal. If each speech
signal is sampled at 16 kHz and PCM quantized by 8 bits/sample, while the music signal is
sampled at 64 kHz with the same PCM quantizer.
1. Draw the block diagram of this TDM.
2. Calculate the output bit rate of this TDM.
You and your crew have made it through the night and the day has brought more warmth. After searching the industrial site, you find an abundant amount of fuel to run the generators to keep you warm. You also find a memory card labelled “cure”, but your cell phone battery is dead. First things first, you will need to stay safe as the zombies continue to hunt you in your current location. The industrial site is surrounded by a metal chain-link fence. You decide you will electrify the fence to keep the zombies from scaling it. But the output voltage from the generators is not high enough to really deter them. You would like to apply around 10 kV to the fence (AC or DC, at that voltage it doesn’t really matter). You find a transformer that you can use but it only has a turn ratio of 10. You find some diodes and capacitors and construct the circuit shown in Figure 3 with the intention of hooking Vout to the fence.
Perform a simulation, displaying the voltage Vout using a scope.…

1. Calculate the magnitude (in RMS) of the current through R1 2. Calculate the magnitude (in RMS) of the current through R2. Simulation 1. Construct the circuit in Figure 2 in the Circuit JS simulator. Note that transformers in Circuit JS may be unstable. It is suggested to draw them by clicking from the bottom left corner to the top right corner and refresh your simulation before taking a measurement. 2. Perform a simulation, displaying the voltage across the voltage source, the current through R1, and the current through R2 in a “stacked” scope. Display the RMS average for each trace. Include a screenshot.
Analysis 1. Compare the simulation results for the currents through R1 and R2. What is the percentage difference between the calculated and simulated value for each? Comment on why there may be a discrepancy.
