Traffic light controller (state table/state encodings)

• Generate state table with symbolic states

• Consider state assignments

24

SA1: HG = 00 HY = 01 FG = 11 FY = 10SA2: HG = 00 HY = 10 FG = 01 FY = 11SA3: HG = 0001 HY = 0010 FG = 0100 FY = 1000 (one-hot)

output encoding – similar problem to state assignment(Green = 00, Yellow = 01, Red = 10)
