1. Design a synchronous updown counter that has the following up and down sequences: (0, 1, 2, 3, 4, 5, 6, 7 & repeat) and (0, 7, 6, 5, 4, 3, 2, 1 & repeat). The counter has a 1bit control input (UD), such that the counter counts upward for UD = 0 and counts downward when UD 1. Use negative edge triggered Dtype flipflops and logic gates to implement the updown counter design. (a) Start your design with a state table. (b) (c) (5 marks) Develop the next state equations and simplify them if required. Show your complete work. Implement and draw the synchronous counter circuit. (13 marks) (7 marks) 1.
