two signal problem

I have a two signals generated through a microcontroller but i want to delay one of them by 180 degrees. Is there a simple method of this using a hardware design.
thanks

Hi,
is inverting one signal an option?
If yes it can be done like this:

Code:

                             VCC
                              +
                              |
                              |
                             .-.
                             | |        .  .--.
                             | |10k     |  |  |
                             '-'        |  |  |
         .--.  .              |         '--'  '
         |  |  |              o---------------o
         |  |  |              |
         '  '--'           ||-+              OUT
                           ||<- BS170
        o------------------||-+
                              |
       IN (from MC)           |
                             ===
                             GND

that will only work provided the signals are symmetrical, like a square wave with 50% duty cycle, or a sine or triangle wave... in the case of a microcontroller it's probably a square wave, so unless it's symmetrical that won't help...
