Circuit Questions

  1. Dec 4, 2004 #1
    I'm not completely understanding the concepts of the 555 timer and the J-K Flip Flop.
    1) For a 555 timer in monostable mode, if the reset signal is at 0, how can I make the output a 1? Or is this even possible?
    2) For a flip-flop switch with timing, can the inputs cause a change when a clock transition is not occuring?
    3) How would I construct a truth table for a flip flop switch?

    Any hints would be greatly appreciated!
