triggering on rising or falling edges?


hello all,

is there a way for me to detect only the rising or falling edge of a
step function??  right now i'm using a conditional test that doesn't
differentiate between the system going from 0 -> 1 and 1 -> 0.  i'd
really like it if the system would only trigger on the 0 -> 1
transition.  does anyone know if this is possible??

thanks,
dan
