These are the questions and my answers for the homework for Lesson 3 of the Digital Electronics course from PyroEdu.

**What are the 3 basic logic gates of digital electronics? What are their symbols?**

The three basic logic gates of digital electronics are the `AND`

, `OR`

, and `NOT`

gates. They are represented by the following symbols, respectively:

**How are the 3 basic logic gates (answer from question 1) different from one another?**

They are different from one another because of both their required inputs and given outputs.

While the `AND`

and the `OR`

gates require two inputs for one output, the `NOT`

gate requires one input for one output.

As with result, the `AND`

gate only returns 1 when both inputs are 1 while the `OR`

gate returns 1 whenever there is at least one 1 value from the inputs.

The `NOT`

gate, as its name implies, simply returns the opposite value of the input.

**Using X and Y as input variables and Z as an output variable, write the three Boolean algebra equations that represents the 3 basic logic gates.**
**What information does a truth table tell us about a logic gate?**

A truth table tells of all the possible inputs to a logic gate and their corresponding output.
