A certain RDC has an 8-bit digital output. What is the angle being measured if the output code is 01001101? The left-most bit is the MSB.
To get the angle represented, add all the included angles (as indicated by the presence of a 1 in the output code).
90.00000^{\circ}+11.25000^{\circ}+5.62500^{\circ}+1.40625^{\circ}=108^{\circ}
Although more digits are carried in the calculation to show the process, the answer is rounded to the nearest degree.
