Fundamentals Of Digital Electronics2

1. The only function of a NOT gate is to

Stop a signal

Recomplement a signal

Invert an input signal

Act as a universal set

A NOT gate is a basic logic gate that has only one input and one output. Its main function is to invert or negate the input signal. In other words, if the input signal is high or true, the output will be low or false, and vice versa. The NOT gate does not stop or recomplement a signal, nor does it act as a universal set. Its primary purpose is to invert the input signal.

2. The output of a 2-input OR the gate is 0 only when it’s

Both inputs are 0

Either input is 1

Both inputs are 1

Either input is 0

3. A logic gate is an electronic circuit which

Makes logic decisions

Allows electron flow only in one direction

Works on binary algebra

Alternates between 0&1 values

A logic gate is an electronic circuit that makes logic decisions by processing input signals and producing output signals based on predefined logical rules. It uses Boolean algebra to determine the output based on the input values. The logic gate analyzes the input signals and determines whether the output should be high or low, representing true or false, on or off, or 1 or 0. Therefore, it can be said that a logic gate makes logic decisions.

4. In negative logic, the logic state 1 corresponds to

Negative logic

Zero voltage

More negative voltage

Lower voltage level

In negative logic, the logic state 1 corresponds to a lower voltage level. This means that when the logic state is 1, the voltage is lower compared to when the logic state is 0. This is the opposite of positive logic, where the logic state 1 corresponds to a higher voltage level.
