1. Using even parity, compute the codeword transmitted using a Hamming code for the data M=10110011100. Suppose that 001001111011100 is received instead of the correct codeword (hopefully, the one you computed above). How does the receiver determine which bit contains the error (is flipped)?

2. Suppose that the following sequence of user data is subjected to bit stuffing, what will be transmitted if the data is framed using the usual delimiter (01111110). Do not use Hamming codes.

User Data: 11111011111100

Tx Data (including frame delimiters): _____________________

3. Suppose that the following sequence of bits was subjected to framing and bit stuffing. What is the original user data, prior to stuffing and framing? There is no Hamming code in the framed stuffed user data.

Tx Data: 011111101111101111100101111110

User Data: _____________________
