The Ultimate Guide to Baudot Code Encoding

What is Baudot Code?

Baudot code is a character set predating ASCII, originally designed by Émile Baudot in the late 19th century. It is a 5-bit code, meaning it uses combinations of five binary pulses to represent characters.

The most common variant today is ITA2 (International Telegraph Alphabet No. 2), which was the standard for teleprinters and telex machines worldwide for decades.

How 5-Bit Encoding Works

Since 5 bits can only represent 32 unique values (25), Baudot code uses two special "shift" characters to expand its capacity:

  • LTRS (Letters): Switches to the alphabetic set (A-Z).
  • FIGS (Figures): Switches to numbers and punctuation.

Historical Significance

Early Networking

Baudot was the foundation for the global Telex network, the first international text-based communication system.

Radio RTTY

Amateur radio operators still use Baudot ITA2 for Radioteletype (RTTY) digital mode communications.

Binary Origin

As a fixed-length binary code, Baudot was a critical step toward the development of modern digital computing.
