One positive side-effect of bipolar encoding is that a bipolar violation (two consecutive pulses or two consecutive - pulses sep
arated by any number of zeros) indicates to the receiver that an error has occurred in transmission. Unfortunately, upon the receipt of such a violation, the receiver does not know which bit is in error (only that an error has occurred). The received bipolar sequence - 0 - 0 - has one bipolar violation. Construct two scenarios (each of which involves a different transmitted bit stream with one transmitted bit being converted via an error) that will produce this same received bit pattern.
