1. Use unit analysis to show that a 100MHz signal has a period of 10ns. (Note that Hz is a derived Sl unit equal to 1/s) 2. The maximum frequency supported by category 7 cable is 600MHz. What is the data period for a 600MHz signal? For the following questions, use the following bit stream (spaces inserted for readability): 0111 1011 0000 1110 Draw the encoded signal as a square wave. Either use a paint program, or draw it by hand. 3. LRZ encode the bitstream 4. LRZI encode the bitstream 5. Manchester encode the bitstream
