What is distortion? .
Amplitude distortion occurs in an electronic signal when the power of the amplifier is not great enough to carry the sine wave to its intended peak amp…lification. If you look at the wave form of a amplitude distorted output signal, it would look like someone had neatly sliced off the top of a hill..
Though amplitude distortion is usually an undesired result, the effect is sometimes used intentionally for audio applications, such as a distorted rock guitar which gives that crunchy rock sound. (MORE)
Distortion on a guitar is achieved in various ways; effects pedals, adjusting you amplifiers channels or by playing the guitar close to the speaker so its picking up its own s…ignal and causing feedback. (MORE)
Perceptual Distortion means the perceptual barriers and differences. It includes: Stereotyping means when we generalize. think of a social group which you may have come… across. we often feel that all the members of the group are alike. This is stereotyping. The marketing application of this perceptual distortion is that the marketeer use umbrella branding. The benefit is that if one product of the brand does well then the others will too. Halo effect - That is judging based on reputation and the image the other person projects. Even if a person may overcome a certain habit or trait, they may still project an image associated with it. Physical appearance - This shouldn't matter since anyone can have good or bad values regardless of their physical features or what they are wearing. The founder of Gateway came to work in a t-shirt and wore an earring when men were expected not to wear them. Yet Gateway was a successful company for a number of years. First impression - Someone might just be having a bad day, and it isn't fair to assume they are like that all the time. Jumping to conclusion - This is reaching a conclusion before having all the information. For instance, a father came home and found a lot of beer bottles in the kitchen sink. He was ready to lay into his son about the dangers of drinking and how he wasn't going to tolerate drinking under his roof. But he restrained himself and asked his son to explain. The son said that he found all those in the yard and didn't want the neighbors to get the wrong impression of their family. (MORE)
Try taking the peel of an orange and laying it out flat so that all the edges meet up - you can't! Well the earth is also a ball and when you try and represent the curved su…rface on a flat piece of paper it would behave like the orange peel. To make a flat map you have to make a projection of the earths round surface (there are a number of ways of doing this) and this introduces a distortion. (MORE)
Distortions are a bit hard to explain but the general idea is that the world is like an orange skin - if you peel off the skin and spread it out (in one piece), then you have …the world and the distortions of maps laid out in front of you. We live on a big ball. Forcing the ball's image onto a 2-dimensional surface is the inevitable problem. Globes are the 'maps' that have the least over-all distortion, but in many ways they have far less detail and practical usefulness than well made 2-dimensional maps. Distortions are also known as projections. Over the years there have been arguments over which projection best explains and depicts the world and in the end, it resulted in the following different projections: .
Wagner VII Projection/Pseudo azimuthal projection .
Conic Projection .
Mercator Map .
And many more.... The importance of distortions very much depends on how a map will be used. If you are planning a country's defense systems and strategies, then you want to eliminate or be able to account for global distortions to the highest degree of accuracy. If you want a good road map that will get you to a destination a thousand miles away, global distortions will mean absolutely nothing to you. Political maps may or may not be improved by paying attention to distortions; sometimes relative areas of adjoining areas will be critical and sometimes not. There aren't going to be many border disputes among the states of the US; it might be different in other parts of the world. (MORE)
While many people will claim globes are not distorted, they often are. All spatial projection have an inherant range of distortion. However, a globe offers the possibality of …no distortion because it is a sphere. Most manufacture do not make a globe that is true to the irregular sphere the earth. (MORE)
