1.12 Exercises
Exercise 1.1: FSM Architecture
Two sequential circuits are given in i gure 1.15. Rearrange each of them according to
the FSM architecture of i gure 1.2.
Exercise 1.2: “
aabb
” Detector
Draw the state transition diagram for an FSM capable of detecting the sequence “
aabb
”
(see example in i gure 1.3) for the following cases:
