Question

The values of the segments 'abcdefg' of seven segment display for the BCD input of '0101'? (Assuming standard segment labeling: a-top, b-top-right, c-bottom-right, d-bottom, e-bottom-left, f-top-left, g-middle. And BCD '0101' is decimal 5.)

• A. 1111111
• B. 0000000
• C. 1011011
• D. 0110011

Hint:

Standard 7-segment display segments: \begin{center} --- a ---
f | | b
--- g ---
e | | c
--- d --- \end{center}
BCD '0101' = Decimal 5.
Visualize or draw the digit '5' on a 7-segment display to identify active segments.

Answer 1

The Correct Option is C

The BCD input '0101' represents the decimal number 5. We need to determine which segments (a, b, c, d, e, f, g) of a 7-segment display must be lit (value 1) to display the digit '5'. The standard display for '5' lights up segments: a, f, g, c, d. Segments b and e are off.
a (top) = ON (1)
b (top-right) = OFF (0)
c (bottom-right) = ON (1)
d (bottom) = ON (1)
e (bottom-left) = OFF (0)
f (top-left) = ON (1)
g (middle) = ON (1) So, the pattern for 'abcdefg' is 1011011. This matches option (c). \[ \boxed{1011011} \]
