Abstract
Communication system may be the fastest growing technologies in our culture today. One of the ramifications of that growth is a dramatic increase in the number of professions – where an understanding of these technologies is essential for success – and a proportionate increase in the number and types of students taking courses to learn about them. Developments in communication technology have increased its application in allied fields of electronics, including computers and industrial control. Regardless of a student’s ultimate area of specialization, knowledge of communications concepts and applications is no longer optional, it is essential to understand today’s multidisciplinary applications. This paper provides a basic methodology of designing Transmission and Reception parts of a speech signal using different electronic equipment’s which can be easily understandable. Then we have applied here a speech enhancement filtering technique using FPGA and finally it is played via headphone.
