I am a graduate Computer Science student with limited knowledge of electronics. I hit a wall in trying to figure out the following problem. I have to design an counter using SR Flip Flops that make the following transitions: 1 to 3, 3 to 5, 5 to 7, and back to 1. See attached for work I have done. I'm not sure I actually need the 3rd SR Flip Flop because the K-map for the 3rd flip flop is coming out strange and I am not sure how to proceed. I apologize if this problem seems simple and basic. Thank you in advance for any help.
