Instrumentation Physics

Physics of Instrumentation is one type of expertise in the field of physics that is more focused discussion on the elements of the means of electrical instrumentation, computing and robotics

Physics of Material

Materials Physics is a container to perform the activities associated with teaching and research in the field of materials that discuss the theoretical study that focused on photonic crystals, functional materials, including nano-inorganic materials, magnetic and superconducting materials, conjugated polymers, and polymer hybrid photonic crystals, development of material applications, including solar cells, light sources (LEDs, Laser), and integrated optical devices for telecommunications.

Geophysics

Earth Physics (Geophysics) is a branch of physics that studies the symptoms of earth and earth to do with the structure of economic interests, such as mining of petroleum, coal or building plans.

Theorytical Physics

Studied theoretical physics and physics developed by using basic principles that have been known, aided mathematics and computer; and predict new things that can be tested through experiment / observation, or to explain this phenomenon results experiments / observations.

Digital system, Simple Defenitions and Understandings

Perhaps many who do not know what is meant by a digital system definition and understanding, and even let definitions and understanding but the form and what its function is still a lot of people do not know. In fact, when viewed from the function and application of all the people in this world already use it and the more ironic they use the functions and applications of digital systems they use every day and to the extent that one uses as one activity of daily and hourly.


Actually, what is a digital system? Well, after I read some books and journals from the internet a language that is easy digital system that is the internet, electronic items, call it like Laptops, computers, LCD TVs, Smart phone, Smart TV, and many other types. however, the definition of a digital system that serves to transform the system (process) Varying signals / random or unclear directions and goals into discrete signals or discontinuous.

Surely, you who are reading this wondering why is converted into discrete signals aka disjointed. Yes, if my very simple answer, order random signals can be selected which produce a good that even though discrete unidirectional signals. But, after I read on the internet are so many reasons why converted into discrete signals. According to e-books Journals Digital Systems, which I downloading from mercubuana.ac.id, The advantages why are converted into digital signals which are:
  • Ability to produce a better signal and accurate
  • Have good reliability
  • Easy to design, requires no special mathematical ability to visualize the properties of simple digital circuit
  • Flexibility and better functionality
  • The ability of a program that is easier
  • At last but not least is Faster than an analog system
Yes as above digital system is used that's why the reasons. Actually, this digital system is really very easy to understand because it is his understanding, the digital system uses discrete signals falter. Surely that is in your mind of course that is called to faltersuch exist and not exist or if the numbering system, you will think like 1 and 0. Well, according to Bambangherlandi.web.id in electronic journals digital,
Digital signals are usually represented by algebraic notation 1 and 0. Notation 1 represents the junction and the notation 0 represents no junction. The easiest example to understand this sense is a light switch. When you press the ON means there is a junction that is denoted by 1 and when you press OFF then it will apply otherwise.
Finally, For the moment, articles on digital systems is still like this because I have to learn first (I know this blog admin Materials Physics studies minor is so must start from zero again if you want to discuss about other areas)
