Abstract
Improvements in the arrhythmic telegraphic receiver transmitters using trivalent modulation, essentially characterized by having a code of 4 impulses, preceded by one of starting and followed by another stop, modulated in three different ways: more (positive current), less (negative current) and zero (lack of current), being therefore its number of signals obtained by variations with repetition of fourth degree with three elements, equal to 81, which, according to the international telegraphic regulations, are distributed as follows: letters (uppercase only), 10 digits and 8 signs, plus those needed for space, warning bell, automatic response, row change, and carriage back when page printing is used, leaving 31 combinations for theº and other applications that create the administrations.
