Homework Help: Is this truth table hitting all the possible cases?

  1. Oct 30, 2005 #1
    Hello everyone, I don't want to implement the rest of this circuit if i messed the truth table up! So i was wondering if someone can take a look to see if the truth table seems to hit all the cases and looks correct.

    Here is what the problem says:
    Inputs:
    <tex>S_i = 0, 1, 2, 3, 4, 5</tex> - signals from six sensors sets (0 - instrution detected, 1 - no intrusion detected).
    M- master switch (0- security system on, 1- security system off)

    Outputs:
    A- alarm (0 - alarm on, 1- alarm off)
    L - lights (0 - lights on, 1 - lights off)
    V - video cameras (0 - video cameras OFF, 1 - video cameras ON)
    C- call to police (0 - call OFF, 1- call ON);

    Thanks!

    n/m, it is right.

    Since you have inputs 0-5 and we only care about when M is on except for the one case when it is off, shouldn't there be 2^(n-1) possibilities or rows for the sensors?
