Test: Digital Electronics- 1 - Question 7

Why is a demultiplexer called a data distributor? 

Detailed Solution for Test: Digital Electronics- 1 - Question 7

A demultiplexer sends a single input to multiple outputs, depending on the select lines. For one input, the demultiplexer gives several outputs. That is why it is called a data distributor.

*Answer can only contain numeric values

Test: Digital Electronics- 1 - Question 10

In the given figure shows a negative logic AND gate. If positive logic is used this gate is equivalent to

Detailed Solution for Test: Digital Electronics- 1 - Question 10

The symbol itself is that of an AND gate; however, due to the presence of the circle (indicating inversion), it is a Negative-Logic AND gate. This means that when using positive logic (where a high voltage represents a logical '1' and a low voltage represents a logical '0'), the gate behaves oppositely to its symbol.

So, if we convert this negative-logic AND gate into an equivalent positive-logic gate, the inversion circle at the output negates the AND operation, effectively turning it into a NOR gate.

Therefore, the correct answer to the question in the image would be:

2. NOR gate

This is because the NOR gate is the positive-logic equivalent of a negative-logic AND gate.

Test: Digital Electronics- 1 - Question 11
