Difficulty: Easy
Correct Answer: a, c, d, e, f, and g
Explanation:
Introduction / Context:
Seven-segment displays represent decimal digits by illuminating specific segments. Knowing which segments correspond to each digit is crucial when designing decoders (for example, BCD-to-7-segment) or when debugging display wiring and logic.
Given Data / Assumptions:
Concept / Approach:
The digit 6 typically lights every segment except b. It shows the top bar (a), both left bars (f, e), the middle bar (g), the bottom bar (d), and the lower-right bar (c). The upper-right bar (b) remains off to distinguish 6 from 8 and 0.
Step-by-Step Solution:
Verification / Alternative check:
Consult any BCD-to-7-segment truth table (common-anode or common-cathode; the active level differs but the logical mapping is the same). Digit 6 has b = OFF in the standard glyph.
Why Other Options Are Wrong:
Common Pitfalls:
Confusing common-anode vs common-cathode wiring (active levels invert) and mislabeling segments, especially b and c.
Final Answer:
a, c, d, e, f, and g
