In a BCD-to-7-segment decoder, what is the minimum and maximum number of segments that can be active at any given time?

Introduction:
The number of lit segments varies depending on which decimal digit is being displayed.

Concept:

Digit 1 lights only 2 segments (b and c), while digit 8 lights all 7 segments. Thus minimum = 2, maximum = 7.

Final Answer:

2 and 7
