d. The 7-bit ASCII code for the character '&' is:
0100110
An odd parity check bit is now added to this code so 8 bits are transmitted. What will
be the transmitted bit sequence for the ASCII character '&'?
If odd parity check bits are used when transmitting ASCII codes, which of the following
received bit sequences are not valid? Explain briefly how you reached your answer
a. 01001000
b. 01011110
c. 01111111
d. 11100111

Answer:

00100110

a and d are invalid sequences because they contain an even number of 1's.

Explanation:

Odd parity means that you want an odd number of 1's in the resulting set of bits. Since there are 3 (=odd) bits in the set, a zero must be added to keep the total odd.
