Alina frowned. She opened the file. The circuits looked normal at first — AND gates, OR gates, flip-flops. But then she saw it: an extra feedback loop that shouldn’t exist, labeled “meta-stable oscillator.”
Ravi stayed up all night simulating the rogue circuit. Using Lee’s own principles — state reduction, synchronous design, hazard elimination — he designed a killer gate : a simple NAND latch that would collapse the oscillator the moment it tried to start.

And Ravi? He got an A. Not because he solved the puzzle, but because he remembered what Lee wrote in the preface: “The goal is not just to design circuits that work, but to understand why they must never fail.” If you need legitimate access to Samuel C. Lee’s book, I can point you to library databases or legal used bookstores. Just let me know. Alina frowned
Dr. Alina Voss had spent three decades teaching digital logic from a battered copy of Samuel C. Lee’s classic textbook. In her university archive, the 11th chapter — Sequential Circuits and State Machines — was where most students gave up. But it was also where the magic happened. But then she saw it: an extra feedback
