Communication System ELTR-253 2nd Year Notes PDF
Preface ;
This Text book Notes is written keeping in view the communicational needs of the students of Electronics Department (2nd Year) studying in TEVTA Technology Colleges. The Text book Notes contains several Pages that cater to the various needs of these engineering students. Every Page has Questions/Answers, diagrams, charts, graphs and pictures which help the students understand the topic easily. The language of the book is kept as simple as possible but all the topics are discussed in detail. As the Diploma students of TEVTA institutes often go abroad, particularly in Gulf countries, there are several topics which help them communicate in those particular foreign settings easily and frequently. Eltr 253 Notes pdf. The special care has been taken to enable Engineering students understand and communicate Engineering terminology easily. As Eltr-253 is a 150 marks paper, the length of the Text book Notes is kept within a reasonable limit. Every chapter covers several topics and every topic is further divided into sub-topics. DAE Notes. Topics are detailed with headings and sub-headings to help students understand and memorize the concept easily. All chapters are followed by exercise which contains long questions, short questions and multiple-choice questions. Last, but not the least, we are grateful to all our colleagues who help us with their precious suggestions to complete the task successfully.
Main;
Communication system is a system model describes a communication exchanges between two stations, transmitter and receiver. Signals or information’s passes from source to distention through what is called channel, which represents a way that signal use it to move from source toward destination. To transmit signals in communication system, it must be first processed by several stages, beginning from signal representation, to signal shaping until encoding and modulation. After preparing the transmitted signal, it passed to the transmission line of channel and due signal crossing this media it faces many impairments such noise, attenuation and distortion. This note book/Text Book Notes gives a brief concepts about transmission line calculation and also provides an idea about communication system impairments with an example for each one. The note book/Text Book Notes also provides an introduction to data communication with a simple ideas of data processing. So far, we have taken the full care to cope with the need of students by adding latest information but we think still lot is to be done which is only possible with the help of students who take care for the improvement of the book for the next generation.
