The RGB Color Model

All visible colors can be obtained by combining red, green, and blue light. The red/green/blue (RGB) color model takes advantage of this fact. The RGB color model, depicted as a cube in Cartesian three-dimensional...

Binary Digital Communications

Binary Digital Communications

The use of binary data provides excellent communications accuracy and efficiency. If multilevel signaling is required, then all the levels can be represented by groups of binary digits. A group of 3 binary digits,...

Digital Circuits

Digital Circuits

All binary digital devices and systems employ high-speed electronic switches that perform Boolean operations. These switches are called logic gates. By combining logic gates, sophisticated digital systems can be built up. Even the most...

Logic refers to the reasoning used by electronic machines. The term is also used in reference to the circuits that make up digital devices and systems. Boolean Algebra Boolean algebra is a system of...

Numbering Systems

Numbering Systems

People are used to dealing with the decimal number system, which has 10 different digits. But machines use schemes that have some power of 2 digits, such as 2 (21), 4 (22), 8 (23),...

Digital Signals

Digital Signals

An analog wave (A), and a digital rendition of this wave (B). A SIGNAL IS DIGITAL WHEN IT CAN ATTAIN ONLY SPECIFIC LEVELS. THIS IS IN CONTRAST TO ANALOG signals or quantities that vary...
