Can all errors be detected? What are
some examples?
No, errors can still occur. For Example (assume we are using ODD parity):
|
Original
Sequence |
Number
'1' bits |
Parity
bit added |
Sequence Sent |
Sequence
Received |
|
0
1 0 1 0 1 0 |
3
(even) |
'0' |
0 1 0 1 0 1 0 0 |
0 0 0 0 0 1 0 0 |
In this example, the message sent is
NOT the message received, but it would not be detected since the total number
of '1' bits received is odd.
