In[] is applied to the D inputs of the flip-flops on the left, Out is the Q outputs of the flip-flops on the right. Note "in" is stable at the D inputs at the end of the clock period they are written in. E.g. Just before the first rising edge of the clock In is 1010 . Specify the missing values of out as 3 hex characters in the boxes, without spaces, e.g. 302 .
