Basic theory on telecommunications

The telecommunication based on other disciplines to obtain powerful tools for modeling different systems that transmit and receive information that makes every communication and implementation to proceed.

MATH: As a formal science, mathematics provides a means to formally express the models involved in the transmission of information and tools for analysis, such as algebra, calculus and differential calculus, statistics ... highlight tools like the Fourier transform or Laplace transform.

PHYSICS: Physics provides the study of the environment around us and on which telecommunication systems are established. Emphasizes electromagnetism. Its mathematical basis was developed by the Scottish physicist James Clerk Maxwell in his Treatise on Electricity and Magnetism (1873), which introduced the concept of electromagnetic wave and allowed an adequate mathematical description of the interaction between electricity and magnetism through fundamental equations describing and quantify the force fields.

INFORMATION THEORY: It allows to evaluate the capacity of a communication channel according to your bandwidth and signal to noise ratio. It was the Bell Labs scientist Claude E. Shannon who with the publication in 1948 of the study entitled A mathematical theory of communication formed the sayings used to describe communication systems mathematical models.

SYSTEMS THEORY AND CONTROL THEORY: These interdisciplinary studies can model the different communication systems. Systems theory models the individual contribution of each element that makes up a system while control theory models its evolution over time, which can be automatic.

COMPUTERS: For setting the communication protocols or simulate.

ELECTRONICS: Telecommunication systems are based on both analog and digital electronics circuits, driven by the massive introduction of integrated circuits, and has allowed fully take advantage of digital signal processing. This can be implemented, for example, filters with which to discriminate certain frequencies of a signal; is what is done by tuning a radio or TV.
