    Hello i have a question not know how to solve it, it's about RCA-4-bit Adder Max and Min Delay
    For example Input values X(X3,2,1,0),Y(Y3,2,1,0)
    C0 is result in the maximum delay for the adder
    Output is formed by C4 S3S2S1S0

    I am not know like this situation
    Input values
    X(4),Y(4),C0 how much?
    output values
    C4,S(4) how much?
    Delay how much?
    what's the reason?

    The same Minmum how much as those values?
