General InformationThe era of digital electronics has become one of the most important developments in society's history. What were once time-consuming manual tasks and processes are now programmed to the point where multitasking is an integral part of our lifestyle. So, what is digital electronics? These are sophisticated devices capable of sending information via electronic signals from point A to point B. Information is transmitted from one circuit to another using electronic currents. However, it is the logic sequences embedded in the electrical circuit that distinguish digital electronics from electronic devices of the past. Binary logic, also known as Boolean theory, implements a basic two-value logic system "true" and "false" to carry information via electrical signals. The electronic gate (circuit) is the source of what makes the electronics work. The electronic gate is where and how an electrical current is sent. The first gate was a relay device invented by Joseph Henry in 1835, the next was a vacuum tube invented in 1904 by Sir John Ambrose. Soon after, transistors were developed, leading to the construction of integrated circuits and microprocessors, of which today's digital electronic components are made. A digital circuit is typically constructed from small electronic circuits called logic gates that can be used to create combinational logic. These doors are the building blocks of all digital devices. Each logic gate represents a function of Boolean logic. Logic gates are a set of switches, better known as transistors. The output of logic gates is an electrical flow or voltage, which can control more logic gates. Looking again......middle of paper......the circuits double approximately every two years. This means that every two years the circuits will become more complex. Thus, more complex printed circuit boards can be created, capable of performing more functions and taking up as much space as their predecessor. Recently, researchers have been experimenting with a new concept called “nano-electronic-fluid logic (NFL).” It is expected that logic gates with NFL offer the potential for much higher switching speed. The NFL works by using surface plasma waves that collide and repel each other. Depending on which direction the wave goes, it can be interpreted as a 1 or a 0. By using NFL in logic gates, the switching frequencies will increase and ultimately create fast signals. If the NFL does not become viable, Moore's Law will remain in effect. So digital electronics will continue to improve and become more complex..
