Ben Bitdiddle has finished his ECE210 lab 8 and he tried to design another similar circuit to detect the sequence "101" without overlapping . Different with the ECE210 lab 8, Ben used Mealy state machine here. Unfortunately, Ben's circuit is not working properly. He left his circuit's block diagram in the figure below. The schematic for the three flip-flops' inputs, i.e., D2, D1 and D0 are missing.
Pleas write the Boolean expressions for D2, D1 and D0 and the output signal O in terms of the signals listed in the table below. Note: If D2/Q2 are not needed, you need write Nil for D2.

Ben Bitdiddle has finished his ECE210 lab 8 and he tried to design another similar circuit to detect the sequence "101"  without overlapping . Different with the ECE210 lab 8, Ben used  Mealy  state machine here.  Unfortunately, Ben's circuit is not working properly.  He left his circuit's block diagram in the figure below.  The schematic for the three flip-flops' inputs, i.e., D2, D1 and D0 are missing.    
 Pleas write the Boolean expressions for D2, D1 and D0 and the output signal O in terms of the signals listed in the table below.  Note: If D2/Q2 are not needed, you need write  Nil  for D2.
