The data to be transmitted is 0b’0001111’ and using even parity. Then, the parity bit would be
The parity bit for even parity is a bit that is added to the data to ensure that the total number of 1's in the transmitted data (including the added parity bit) is an even number.
In this case, the transmitted data is 0b'0001111'. The number of 1's in this data is 4, which is an even number. So, the parity bit would be 0 to maintain even parity.
Therefore, the final transmitted data with the added parity bit would be 0b'00011110'.
