Q.3) You want to transmit the message +8 a. Encode this textual message into a sequence of bits, using 5-bit ASCII coding, followed by a sixth bit for error detection, per character. This bit is chosen so that the total sum of the six bits using XOR gate is one. How many total bits are there in the message? b. Assuming the bit duration c. Assuming the bit duration 10 ms, plot the NRZ-M code. 10 ms, plot the Bipolar-RZ code.

Question 1. and {C,D} form the two 2-bit numbers N1 and N2. The circuit will perform the difference N1 – N2 and gives output bits F (MSB) and G. Assume that the circuit never sees the combinations of inputs in which N1 is less than N2 i.e. you can regard those input combinations as don't care Consider a 2-bit binary subtractor defined as follows. The inputs {A,B} conditions. а. Fill in the truth table for F and G. b. Fill in the K-map for the minimum sum of products expressions for the function F and G.

3. (a) What is Checksum? Can a checksum be used to detect errors correctly 100% of the time? If we want to be able to detect three-bit errors, what should be the minimum Hamming distance? 3. (b) A sender needs to send the four data items 0x0236, 0×0BCC, 0×03BC, and 0XEEEE. To avoid confusion, Ox is written in the prefix to denote that the data is in Hexadecimal. For example, Ox3456 is 3456 in hexadecimal. Now answer the following: i. Find the checksum at the sender site. li. If the second data item is changed to 0XABCD and the third data item is changed to 0X04BD during transmission, check if there is any error at the receiver site.
