Hi, thank you for landing on this article. This article is based on the Information theory that has been used in coding. This article will help you to understand about Information theory and Coding by GIRIDHAR PDF. Information theory by GIRIDHAR PDF plays a major role in our daily life. One of the examples is when we use the internet to browse or download any data. The Data rates affects how fast we can download or watch videos using an internet connection. But the Data rates are not same for all internet provider. Let say if you are using an average speed internet connection then you have to wait 5 minutes to download a 1 minute video. But if you are downloading or browsing using a data package of certain internet providers then it takes less than 1 second to download the same video. This is because your internet connection is equipped with information theory features like capacity and data rate limit. Information theory by GIRIDHAR PDF has been used in many different situations like in satellite communication, marine communication and even in our daily life we use it when we speak on phone, send mail or browse through internet. Information Theory by GIRIDHAR PDF It is a part of communication technology that deals with different features. It also deals with data rate and capacity of the channel. A channel is an information flow path in which information is transmitted from one point to another. Here in this article, we will be covering all these points like total no of symbols, noise in the channel, data rate, capacity etc. Theory on noise in channel: Noise in channel is always there when you are using this for transmission purpose like if you are using mobile internet then it has varying signal strength depending upon your location. The distance between transmitter and receiver directly affects the noise level in the channel. Noise in channel is continuous, it has different sources of noise like thermal noise, atmospheric noise etc. Theory on Data rate: Data rate plays major role in sending data from one point to another. Different types of information theory are used to send or receive information at faster rate. Like if you are using the landline telephone then it will take lesser time to download data because you are connected with copper wire which is having some type of information theory features. The Quality of transmission also depends upon these features. If the distance is too long then the quality will be bad because of fading effect in FM or AM modulation techniques, but if you use satellite communication then they have better quality than the conventional ones. Theory on Capacity: Capacity of a channel depends upon the distance and number of channels at the receiver. Capacity of a channel also depends upon the frequency and peak power used which is needed to send or receive information. If we compare with Radio, this is not related to any mathematical formula, but still it has some type of information theory features which can be compared with radio waves. Radio wave length plays a major role in conveying data from transmitter to receiver. The term Amplitude is used here rather than bandwidth because it is representing frequency rather than wavelength This type of spectrum spans from 0 Hertz (Hz) (a single tick mark) till 1 Tera Hertz (hz). cfa1e77820
