I managed to solve the 4 way and 8 way multiplexors, but im stuck on the multiway dmux. I figured i could do much the same as with the mux, i drew a diagram using a dmux with its input as sel[0] and its sel a sel[1] which chooses between dmux a& b and dmux c&d , which seemed to make logical sense at first. I figured i could wire the input to go to both and then using the first dmux i could select which would be activated.. but im beginning to think that is totally wrong, the dmux will set a value in both second level dmuxes regardless. Am i on the wrong track thinking to use a dmux as both selector bits? should i be looking for something similar to the mux's ?
