    I would like to know how we can analyze the fault using

    look at this pdf file
    I Image 1st
    Fault-free function z = AB+CD
    Faulty function zf = AB

    Fault-free function z = AB+CD
    Faulty function zf = AB+D


    TABLE]


    Code ( (Unknown Language)):
    1. A  B  C  D  Z   ZF
    2. 0   0  0  0  0   1
    3. 0   0  0  1  0   1
    4. 0   0  1  0  0   1
    5. 0   1  0  0  1   0
    6. 0   1  0  1  0   1
    7. 0   1  1  0  0   1
    8. 0   1  1  1  0   1
