1. A band limited signal with maximum frequency 1000 Hz is sampled at the Nyquist rate of 2000 samples per second. It is then quantized to 8 levels. What is the bit rate of the coded signal? Repeat for 32 levels and 64 levels. How does the increase in number of level p affect the bit rate of the coded signal?
2.10 band limited signal (1000 Hz) are sampled at the Nyquist Rate and then quantized to 16 levels. Calculate the pulse width of each bit to support the multiplex of these 10 signals. Calculate the bit rate. Repeat for 100 signals. (2 marks)
3. What would happen to the Capacity C and the communication rate if there is no noise on the channel?
