1. The following message was originally transmitted with odd parity in each short bit string. In which strings have errors definitely occurred?
11001 11011 10110 00000 11111 10001 10101 00100 01110
2. Suppose a 24-bit code is generated by representing each symbol by three consecutive copies of its ASCII representation (for example, the symbol A is represented by the bit string 010000010100000101000001). What error correcting properties does this new code have?
3. Using the error-correcting code describe, decode the following words:
a. 111010 110110
b. 101000 100110 001100
c. 011101 000110 000000 010100
d. 010010 001000 001110 101111 000000 110111 100110
e. 010011 000000 101001 100110
