CURRICULUM FOR B.E. COMPUTER SCIENCE AND ENGINEERING

AIM:
To give an understanding on the study that deals with the representation of signals as
ordered sequences of numbers and how to process those ordered sequences.

OBJECTIVES:
  To understand the basics of signals and system by analyzing the various transformations available and determine their use to DSP
  To study on the various digital filtering techniques and how to apply to DSP
  To study on the ways to estimate signal parameters, and transform a signal into a form that is more informative.
 To give students a flavour on the applications of DSP in the areas of speech
