Interrupt-driven circuit

  1. Apr 27, 2011 #1
    I'm much more of an analog guy myself, so I'm wondering if you guys can help me out. I am looking to design a digital circuit which takes two inputs, and has one output.

    I want the following behavior:
    Whenever either of the two inputs changes value, the output changes value. Assume that the two outputs never change at the same time, and that there is enough time between changes that any circuit response time is negligible.

    Does anyone have any idea how this can be accomplished?

    Okay, I am a bit chagrined to admit I was stumped for a while before posting, but I just figured it out. I can use a simple XOR gate - any transition in a single input results in a transition of the output.
