04.125pts) Design a combinational circuit that controls the traffic lights Red (R), Yellow (Y). Green (G) using a binary counter. The circuit works according to the following table: Counter Lights Ris ON (Yand Gare of R and Yare ON (G is oft) Gis ON (R and Yare off)

Answer 1

4. According to question, - Red Green Yellow counter output o cool I (01) - - * хоо 2 (10) o 3 (11) (since we no information took status is of given LED for as counter value Don't care for o it) 89 m 0 0 ola Y- 3 G = R=2A + 2B - 2.23 Now we skip this Present state design our counter (If you don't need this, part): we'll use D- Flip Flop for this (0 FF input) Next state Excitation on Q3 ont 2, DADE oo o 1 0 1 1 0 1 0 10 , 11 0 1 0 1 -

solving VB 28 23 QUI DI DB = PA + 2B DA = 40 + TA Q3 = QA 23 counter is, So our La Light

we draw our circuit counter How MA Green
