011010000001110011 The above data will be transmitted by using digital signal. The encoding technique used has following features. - Having differential encoding - Having no synchronization - Having DC component a. Draw encoded signal of this data. (Assume that the last received signal element was in low signal level) b. If the modulation rate of this technique is 40KBaud, how much time is required to transmit the 2 MByte sized file? c. When the above data transmitted by using Bipolar-AMI and HDB3 encoding: Receiver recognized the error occurred in 5 th bit from the right-hand side after checking 2 nd bit from the right-hand side. How did it detect this error? Display with drawing the signal and explain it. Can it be corrected? Why
