Module 5. Digital techniques / Electronic instrument systems

An octal format hexadecimal number 3F written as binary would be

  • 110 111.
  • 111 111.
  • 101 011.

Explanation

Each hexadecimal digit expands to four bits, but only six are needed here: 3 is 0011 and F is 1111, so 3F is 00111111, i.e. 111111. The marked grouping 111 111 is correct.

RiccardoPetre asking:

F=15, so 3 is (0011) and 15 is (1111), so full binary number is 00111111, remove (00) from fwd because it is not important and you will get you answer 111 111.
