Hi Dr Casas,

I was studying the notes about the RS latch and D flip-flop and was a little bit confused.

Is it possible that we are asked to use RS latch to control a state machine instead of using a D flip-flop ?

For the Guarage Door question in the assignment, should we draw a D flip-flop in the schematic diagram...? (because it was not drawn in the solution handout)
Can we use RS labth instead of D flip-flop in the controller for this question...?
If we can, could you simply explain how...?

thank you
