The '''Baudot code''' ({{IPA|fr|bodo}}) is an early [[character encoding]] for [[telegraphy]] invented by [[Émile Baudot]] in the 1870s.<ref>{{Citation | editor-last = Ralston | editor-first = Anthony | editor2-last = Reilly | editor2-first = Edwin D. | year = 1993 | title = Encyclopedia of Computer Science | chapter = Baudot Code | edition = Third | publisher = IEEE Press/Van Nostrand Reinhold | location = New York | isbn = 0-442-27679-6 }}</ref> It was the predecessor to the International Telegraph Alphabet No. 2 (ITA2), the most common [[teleprinter]] code in use before [[ASCII]]. Each [[Character (symbol)|character]] in the alphabet is represented by a series of five [[bit]]s, sent over a [[communication channel]] such as a telegraph [[wire]] or a [[radio signal]] by [[asynchronous serial communication]]. The [[symbol rate]] measurement is known as [[baud]], and is derived from the same name.
