It's been so long that I've forgotten what I used to use when I was an electrical engineer, but I would suggest a leading underscore instead of a trailing one; i.e., '_A', not 'A_', for the benefit of people who would pronounce the inverted form of signal A as 'not A' rather than 'A bar'. You could also consider '!A' given the wide use of '!' for logical negation in programming languages. There's also some use of '~' as 'not', or you can be technically correct and confuse many of your readers by using ¬, NOT SIGN.
