In the line coding scheme 2B1Q, the r is equal to Hint: r = the number of the data elements/the number of signal elements. To line encode 00 in 2B1Q we need to find out the polarity of the previous signal element. Assume that the previous signal level is positive, then 00 is encoded as and 10 is encoded as Question 4 1.5 pts Transmission systems are classified into one of four quadrants: Digital Data/Digital Signal(D-D), Digital Data and Analog Data/Digital Signal (A-D). RS-232 belongs to /Analog Signal (D-A), Analog Data/Analog Signal (A-A) Ethernet to and Wi-Fi to Question 5 1.5 pts The Analog to Digital conversion consists of 3 steps. These are and
