2. Encode the data stream 1100101 using Manchester line coding. State any required assumptions (such as the value of the previous bit, if necessary) in your solution. Please be neat and show baud intervals. 3. Analog data contains frequencies from 2000 KHz to 5000 KHz. We wish to convert this to a digital signal using Pulse Code Modulation. What is the minimum sampling rate? 4. In Pulse Code Modulation (PCM), we take 2000 samples/sec. Each sample is then rounded to the nearest number that can be represented by 16 bits. What is the bit rate of the PCM output? 5. A perfect channel accepts frequencies between 100 MHz and 700 MHz and transmits a signal with 8 signal levels. What is the channel capacity? 6. A noisy channel accepts frequencies between 100 MHz and 700 MHz and has a signal to noise ratio of 31 (not in decibels). What is the channel capacity
