Q1. Choose the correct answer 1. With fixed number of quantization levels in PCM, the quantization noise is (linearly proportional to signal amplitude, non-linearly proportional to signal amplitude, linearly proportional to signal frequency, non-linearly proportional to signal frequency). 2. A PCM encoder uses 130 quantization levels. Which of the following N bits is more economical to encode such signal? (N=6, N=7, N=9, N=10). 3. Frequency Shift Keying can be accomplished by _multiplying two On-Off Keying signals, combining two Frequency Shift Keying signals, adding two (adding two On-Off Keying signals, Frequency Shift Keying signals). 4. Which of the following statements is true with respect to PCM? (The parallel binary data is converted into serial before transmission, Analog data is transmitted directly, Analog signal is amplified before transmission, The analog signal is converted into parallel binary data before transmission). 5. A baseband speech signal of maximum frequency of…

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.…
