Number of Rows in a BCD Decoder Truth Table
The number of rows in a BCD (Binary Coded Decimal) decoder truth table can be calculated based on the number of input variables. In a BCD decoder, the input is typically a 4-bit binary number, which can represent decimal numbers from 0 to 9.
Explanation:
- Each input variable has 2 possible values (0 or 1).
- For a 4-bit input, there are a total of 2^4 = 16 possible combinations.
- However, since the BCD code only represents decimal numbers from 0 to 9, only 10 of these combinations are valid.
- Therefore, the truth table of a BCD decoder will have 10 rows corresponding to the 10 valid input combinations.
Correct Answer:
- The correct answer to the question is option 'D' - 10 rows in the truth table of a BCD decoder.
By understanding the binary representation of decimal numbers and the constraints of the BCD code, we can determine the number of rows in the truth table of a BCD decoder. This knowledge is essential for designing and analyzing digital circuits that involve BCD decoding.

In BCD to 7-segment Decoder, the outputs of a digital circuit are often displayed as decimal digits.
BCD to 7-segment decoder is a combinational circuit that converts a BCD number into signals that are required for the display of the value of that number on a seven-segment display.
The number of input lines is 4.
Notes:
The decoder outputs are (a, b, c, d, e, f, g)
For the display of the digit 0, segments a, b, c, d, e, f will be lit as shown above.
A truth table can be formed for all digits from 0 to 9.
