Create a decade counter using Toggle flip-flops. The sequential circuit should contain four flip-flops whose outputs form a code word interpreted as a BCD-coded decimal value (0000 for 0, …, 1001 for 9). On each clock pulse, the coded value is incremented, and when it reaches 9, it returns to 0 on the next clock pulse. On the 9-to-0 transition, the circuit activates an output line (c) to indicate the counter overflowed. (LO2, LO3) Question 1. Show the state diagram for the circuit you are going to create. Question 2. Show the state table for the circuit you are going to create. Question 3. Show the Karnaugh map for each input of each flip-flop. Obtain Boolean expressions for the flip-flop input functions.
