The term “decibel” has been used for quantities for which it is not the assigned designation. Confusion and error have resulted. To restore precision and stability to our technical terminology, it is recommended that this term be assigned specifically to unit transmission loss and that the word “logit” be used for standard magnitudes which combine by multiplication. Thus logit would serve as a companion to the word “unit” now used for standard magnitudes which combine by addition.
