Question 11

An 8-bit flight controller on a micro-drone aggregates raw telemetry data from three onboard sensors. During a stabilization routine, it must calculate the sum of the following three unsigned 8-bit binary integers, representing the three sensor readings:

0 0 1 0 1 1 0 10 1 0 1 1 1 1 0+ 0 0 1 1 0 0 1 1 \begin{array}{r} 0\ 0\ 1\ 0\ 1\ 1\ 0\ 1 \\ 0\ 1\ 0\ 1\ 1\ 1\ 1\ 0 \\ +\ 0\ 0\ 1\ 1\ 0\ 0\ 1\ 1 \\ \hline \end{array} 0 0 1 0 1 1 0 10 1 0 1 1 1 1 0+ 0 0 1 1 0 0 1 1​​

Calculate the sum of these three 8-bit binary numbers, showing your working (including carries), and give your final answer as an 8-bit binary pattern.
