Reconsider the three bit synchronous counter register described in the lecture notes. Use the counter symbol to control the lights of a street intersection. Street 1 has lights G1, Y1,

R1 and street 2 has lightsG2, Y2, R2. ) Draw a schematic using the counter to make a counter that counts 000 to 101 and overflow back to count 000. There is a clock input and negative logic clear signal clrn. The reset state is 000. b) The following table shows that each light is green for two units of time, yellow for one unit of time, and red for three units of time. The u symbol indicates unused states.
