BCD Code: Binary Coded Decimal

In order to share information in digital format, it is common to use a binary or hexadecimal representations (BCD Code). There are other methods to represent this information and one of them is the BCD code.

NOR logic gate

A NOR logic gate can be implemented with the concatenation of an OR gate and a NOT gate. NOT gate using a NOR gate. Truth Table

Binary to Gray Code Conversion and Gray code to Binary Conversion.

Two Methods. One method to convert from binary to gray code and another to convert from gray to binary code

The binary number system

The binary number system. unlike the Decimal number System, where they are allowed 10 digits (0 to 9), you only need two (2) digits: “0” and “1”.

Boolean Algebra – Introduction and Rules.

Boolean Algebra is a tool to reduce logical expressions. It is the mathematics of logical expressions, which was presented by George Boole in 1854.

What is a Binary Decoder?

The binary decoder is a device that accepts a digital input (in binary form) and it activates one of its outputs. This device has several outputs, and the one that is activated is chosen by the code applied to the inputs.

The logic NOT Gate The logic NOT gate or Inverter Gate is a logic gate that has only one input and one output. The output logic level is the opposite of the input logic level. The symbol and the truth table of the NOT gate are shown bellow. This gate is represented by the following Boolean function: X = A’. Look at the […]

What is a logic Circuit?

A Logic circuit uses two logic levels to transfer the information. A hight logic level or “1” and a low logic level or “0”. The Logic circuits are made of digital elements such as the AND gate, the OR gate, the NOT gate and a combinations of them.
