1.0 Introduction
In the world today, the scientific and technological progress of any nation depends on it's ability to measure, calculate and finally, estimate the unknown. Also, the success of an engineer or technician is judged by his ability ti measure precisely and to correctly interpret the circuit performance. So as the world goes computerized, the need of electronic mostly become very important to human being, in the sense that we need to have the knowledge and it's basic principle for a better living in the society.
Our satisfaction mostly depend on the so called electronics, for instance, one can communicate with another person elsewhere through the work of telephone. Again, information can be transmitted by means of a microphone which accept the audio frequency, usually of low frequency which inturn being raised to a high frequency with the help of carrier wave to reach a receiver at a very distance destination.
The study of electronics also involves the studying on how electrons moves invisibly. By its definition, Electronics is the study of science and Technology of Electronics Phenomena and System such as Radio, Computer, Television etc.
Finally, in view of our project topic, it works electronically and transmit voices or sound that makes sense to listeners at a very distance destination.
