    Hey guys

    My teacher taught us how to use flip flops as a binary password controller.
    The main idea is, if the binary word is inserted correctly, the FF system gives a High logic signal at its output, otherwise, the output is Low.

    Anyway I tried to build the circuit for a specific word in Multisim, but i just can't get it to work.
    I was told that each bit in the word should be inserted when the CLK is at high edge, and so I used switches as shown in the link below.

    This specific system is supposed to do the following: "Output = 1" if "input code is 10", else, "Output =0"

    Apply a 1 to the input, then clock it, then apply a 0 to the input (it doesn't matter if you clock or not after the 0).
