The Cochin University is one of the foremost institutes of the south imparting technical education. The field of engineering is a very diverse one and involves a number of offshoot branches. The computer science engineering is one of the most sought after branches of engineering in the country.

Importance of the paper

The computer science engineering is a branch of non conventional engineering. It stresses a lot at the innovative skills of the student since the computer industry is still in the phase of evolution. Thus the paper largely deals with the question that test the innovative skills of the candidate in the field of the transmission and reception of the digital signals and their coding and decoding at the sites of transmission and reception respectively.
