Question 4: (20 points) Design a "synchronous BCD counter" with 4 negative edge-triggered T flip-flops A, B, C and D provided with a clock. (0 Draw the state diagram of the counter. (i) Build the counter's state table showing the synchronous inputs of the T flip-flops (ii) Using Karnaugh maps, find the minimal sum-of-products form (SoP) of the as well. equations for the inputs to the flip-flops; assume the next states of the unused combinations to be "don't care states" (iv) Draw the logic diagram of the counter
