How many bit code is used by Murray code for TELEPRINTER machines.

  • A.4
  • B.5
  • C.9
  • D.25
  • E.None of the above

Answer: B

Correct answer: 5

The Murray code, the teleprinter code standardised as ITA2, uses 5 bits per character. That gives \( 2^5 = 32 \) patterns - too few for letters, digits and punctuation together, so two of the patterns shift the machine between a letter case and a figure case, doubling the effective set.
