 Design a traffic light that will display the colors red, green and yellow for a specified amount of time.

 At the count of (0-6) the green light will appear

 At the count of (7-10) the yellow light will appear

 At the count of (10-15) the red light will appear

Requirements

 Create a four-input truth table with 3 output columns for all 3 colors: green, yellow and red. The output columns for the colors will be high when the count reaches the specified range for that color, i.e. if the truth table is counting a 6, the output for the green column should be high or if the truth table is counting a 12, the output for the red column should be high.

 Generate the un-simplified and simplified Boolean expression from the truth table by looking down each of the output columns for the 3 colors: green yellow and red.

 Create a sequential logic section in Multisim. This will be a 4-bit synchronous counter with a count range of 0-15.

 Create a combinational logic section in Multisim. This will be the simplified Boolean expressions for each of the 3 colors: green, yellow and red. Each of the 3 output gates should be connected to an LED that corresponds to the 3 traffic light colors. There should be NO SPDT switches used. The Q and Q NOT outputs of each of the 4 flip flops in your sequential logic section will serve as the inputs for your combinational logic section.
