You and a friend are using the C(7,4) Hamming code to send
some 4-bit messages to each other.
(a) You encode the message 1010 and send the encoded 7-bit
sequence to your friend, who receives 1011011. How many errors were
introduced during transmission?
(b) You subsequently receive the encoded sequence 0111011 from
your friend. Assuming at most one error, what is the 4-bit message
that your friend sent?

if didn't understand anything
feel free to ask me . If you like my work thumbs-up
NOTE: this is at 5th position..not 4th
Using the Hamming code algorithm (7, 4), convert a data message
(0110) using 7bit.
Identify the number of parity bits needed
Evaluate values of parity bits
Final message bits with parity bits
Inject error (o or 1) at 5th position and identify
the error position.

messages CONTINUOSLY without the the other side needing to a
response. Use a send and receive thread to allow this.

Given the 21-bit even-parity Hamming code: 0 1010 0111 0011 0000
0101
and assuming there is one incorrect bit.
a. Which bit is incorrect?
My educated guess for what the incorrect bit maybe has me
thinking it is the '1' bit at the end of the '0111' byte, but I
have no full proof as to why it is that specific bit. Am I in the
right area to think that?
b. After the error is corrected, what decimal number...
Generate a transmitted dada sequence for “101010” using Hamming
code? If an error occurs in the third bit, the received data is
101011”, how would Hamming technique fix it?
Design and Test an 8-bit Adder using 4-bit adder. Use
4-bit adder coded in class using full adder that is coded
using data flow model. Use test bench
to test 8-bit adder and consider at least five different test
vectors to test it.
