Question 1

An embedded microcontroller's sensor interface records three consecutive 8-bit unsigned readings representing the vibration frequencies of an engine component. To calculate the total cumulative frequency, the three readings must be summed.

The readings in binary are:

0 1 1 0 1 0 1 00 1 0 0 1 1 0 0+ 0 0 1 1 0 1 0 1\begin{array}{r} 0\ 1\ 1\ 0\ 1\ 0\ 1\ 0 \\ 0\ 1\ 0\ 0\ 1\ 1\ 0\ 0 \\ +\ 0\ 0\ 1\ 1\ 0\ 1\ 0\ 1 \\ \hline \\ \hline \end{array}0 1 1 0 1 0 1 00 1 0 0 1 1 0 0+ 0 0 1 1 0 1 0 1​​

Add these three binary numbers together and give your final answer as an 8-bit binary number. Show your working.
