Q.3) You want to transmit the message &$ a. Encode this textual message into a sequence of bits, using 6-bit ASCII coding, followed by a seventh bit for error detection, per character. The seventh bit is chosen so that the total sum of bits using XNOR gate is zero How many total bits are there in the message? b. Assuming the bit duration 10 ms, plot the Dicode RZ line code. c. Assuming the bit duration = 10 ms, plot the Bi--M code. d. Assuming the bit duration 10 ms, plot the Miller line code.
