Hey! So I have been trying to pass chapter 3 but I am really failing.
I tried to implement the bit chip but was completely lost.

I had to see the implementation online, I am really trying to avoid looking the rest online, and still I didn't understand.

It used a DFF (which at least this one I understand) but after it used a MUX and an OR.
Ok I know that the DFF has a time delay so it's waiting for the tick/tock from the clock and since the MUX and OR chips don't have to wait for the clock they will click going and going they will be just generating garbage but how does the DFF use the out from Mux which also used the out from DFF??

I am really sorry if I am missing something obvious, I don't know how many times I have read chapter 3, I might have gotten something wrong in the other chapters.

Any other resource I can search? I have read the Lecture notes!
