Study the truth table shown below used to define the requirements for a 2-bit ASR/noS circuit (circuit not shown). Now, complete the truth table for and then develop a SDL circuit definition for the 3-bit ASR/noS circuit. Draw your circuit before starting to code SDL. Use the driver program you find on Blackboard to test your circuit design. Note The SDL file name must be Part2B.sdl.
