digital logic design

3. Design a synchronous BCD Counter based on the following conditions. If last digit of your Roll No is EVEN, then Design an UP counter with JK-Flip Flops by initializing the counter with last DIGIT and count next five states. The counter should cycle back after counting five states. If last digit of your Roll No is ODD, then Design the Down counter with JK-Flip Flops by initializing the counter with last DIGIT and count next five states. The counter should cycle back after counting five states. uuuuu uuuunnnuun Juunuuu Perform all necessary designing steps (Each step carry marks) [CLO4] (12 marks
