🔍 Key Concepts

• Positive logic (what "high" and "low" represent in terms of 1s and 0s) • How the specific logic gates in the figure affect signals (e.g., AND, OR, NOT, NAND, NOR) • Signal flow from inputs through each gate to test points A, B, and C

💭 Think About

• Starting from the given input levels, what is the output of the first gate feeding point A? Then, how does that affect point B? • If a gate inverts the signal, how do the highs and lows change as you go from input to output? • Are there any gates whose output can only be high if all or any of their inputs are high?

✅ Before You Answer

• Make sure you correctly identify which gates are inverting (e.g., bubbles on the output or input). • Confirm what is connected directly or indirectly to each test point A, B, and C before deciding their logic levels. • Verify that you are consistently treating high = logic 1 and low = logic 0 under positive logic.
