Homework Help: Distinct values represented with boolean-valued signals

  1. Jan 28, 2015 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution

    I'm trying to parse what the second and fourth questions are asking.
    I clicked on "preciate" and "proposition" in the wikipedia link and got lost

    As a starter, what is an example of a "distinct boolean-valued functions"

    and one example of a "two boolean-valued signals" ?

    I have a different take than the post on stackexchange, which might or might not be correct. For a boolean-valued function of two boolean signals (second question) there are four distinct arrangements of the two arguments:
    f(T, T)
    f(T, F)
    f(F, T)
    f(F, F)
    Each of these could result in a function value of either T or F, making a total of 8 different possibilities. For the fourth question, using a similar analysis, I get 16 different possibilities.
