Definition of Oscilloscope

In this article I am going to explain about the definition of Oscilloscope. Not many people know what the use of an oscilloscope is. Actually oscilloscope plays important part in our life. It is powerful instrument that we can find in many places for similar purpose. An oscilloscope is used to read signals being observe. By using oscilloscope we can know the frequency, period, and voltage of a signal. By adjusting the oscilloscope, we can also see the difference of phase between in and out signals. There are two main parts of an oscilloscope: Display The display is intended to monitor the signals which are analyzed by the oscilloscope. On the display we can see the vertical and horizontal lines forming boxes that we call div. the horizontal line represents the time base while the vertical line represents the voltage. Control Panel The control panel contains buttons to adjust the display on the screen. Commonly we find oscilloscope consisted of two canals that can be used to read two different signals. Before an oscilloscope can be used to read signals, you have to set it to lower the possibility of error during measurement process. Usually you will find several buttons in an oscilloscope like intensity, focus, trace rotation, voltage/div, time/div, AC/DC, position, ground, and channel 1/2. We will explain the use of each button. Intensity is used to adjust the color brightness, Focus is used to adjust the focus, Trace rotation is used to adjust the tilt of Y axis = 0, Voltage/div is used to adjust the voltage per one div, Time/div is to adjust the time per...

What Is The Definition Of Social Media?

Before you start, you should know the definition of social media first. Following some sources in the internet, social media are media for social interaction, using highly accessible and scalable publishing techniques. It uses many modern technologies which base on web to transform and broadcast medai monologues into social-media dialogues.   To most people, when the words social media are mentioned, Facebook, Twitter and the likes come to mind. So where does marketing comes in when using those aforementioned sites?   When doing marketing, one of few things you have to think is finding a right tool or medium to promote your stuff. And what is more effective than shouting your stuff on Facebook or tweeting it on Twitter!   Social media marketing (SMM) is quickly becoming the most popular way of branding and selling your product or service on the web and there are lots of advantages on it.   One of them is having a widely diverse audience. Everyday, millions (and counting) of people around the world signs up and logs in on their FB or Twitter accounts and spends 10 minutes, at least, their time in it. Every site or business that wants to expand and become profitable, needs a core group of supporters who will be willing to make purchases or recommend your business to others. The more supporters you have, the faster word spreads about your business.   Another thing with SMM is that, it is cost-effective. Since signing up on those social media sites is free, you don’t have to worry about paying some ad agencies to run some ads of your products....

The Definition of Green

I had occasion today to encounter a question that was very simple yet profound. It was “What is the standard for Green?” The EPA has recorded the 12 Principles of Green Chemistry, but these are not universal. If you ask a person interested in the biosphere type of Green, the phrase “Sustainable” is the major issue, questioning whether will an item’s use will be depleted or can it be sustained naturally. Sustainability is a big issue in a world of consumerism, but does not encompass the definition of Green for other areas of Green concern. Those interested in the oceans are concerned about “Marine Life” and how man has impacted the animal life in the oceans. It looks at the discharges poured into rivers, lakes, and the oceans asking if we are harming the animals that feed us. If mercury goes into the water, will it return to us in the tuna we eat at lunch? So, the pollution of the water is a part of the Green definition. “Green House Gases” seem to preoccupy those concerned about the atmosphere. In an industrial world, the manufacture of the things we wish to market creates a lot of waste that we need to dump somewhere. The EPA has long fought the dumping of chemicals from manufacturing plants and the amount of pollutant coming out of the smoke stacks of our factories. Those concerned with the preservation of nature argue that the Green movement stems from the preservation of the tree, forest, plains, and natural habitat from the forces of developers. From the energy side of Green, we are concerned about...

The Definition of Life

The Definition of Life What is the definition of life? Many scientists and biologists define life as living organisms. They assume or believe that life can only exist in living organisms. This might be a specialized definition of life but we are concerned with the more general view or definition of life. For me this definition is too narrow to define the life of everything that exists, For example, the life of human beings, animals, birds and of course the life of all living organisms, life of earth, stones mountains, because we know that the mountains and earth (continents) moves from one place to another with the passage of time and it is scientifically proved also there may be a chance that something that exists 10 years ago may not exist today. So we need to know the life of every thing that exists either living or non-living. The definition I want to give is in generalized form that will define everything. Note that every object in this universe takes time to change or to distinguish. From object we mean that an object could be anything from the very smallest element like atom to a big form like chemicals or solids. This means that the time factor should be included in the definition of life. The new (my) definition of life depends upon two mutually exclusive possibilities this means that either of them should exist and only one at a time. The assumptions are: 1 Rationality. 2 Irrationality. First of all I will explain the concept of rationality and irrationality 1 Rationality:- Rational means logic...

Blood Pressure Definition

The heart organ is a muscle that pumps blood throughout the body to deliver oxygen and nutrients. The pathways the blood travels is through vessels called arteries. Each time the heart beats it pumps blood through the arteries. As the blood flows through the arteries a pressure pushes against the outer wall of the arteries. This pressure pushing against the wall of the arteries is the blood pressure during a half cycle. To be exact the medical term is systolic pressure. To simplify systolic pressure, all it signifies is the blood pressure as the heart contracts, pumping blood. When checking blood pressure (BP) it’s good to know the pressure as the heart contracts and when the heart relaxes. As the heart relaxes it fills with blood which occurs rapidly and is called in medical terms, the diastolic pressure. The actual blood pressure definition is the measurement of the systolic pressure and diastolic pressure. BP is taken with a BP meter. Generally, the BP is taken on the upper part of either arm where a major artery is located. But can be taken on other parts of the body. The meter measures the BP at its high point and low point of the heart cycle. This is the contracting and relaxing of the heart, similar blood pressure definition. The reading is in numbers measured in millimeters of mercury. The blood pressure definition in terms of the numbers from the BP meter is the first number will be the systolic pressure (contracting heart) and the second number the diastolic pressure (relaxed heart). What this means to you is if these numbers vary from your natural BP reading. Some...
