Implementation of various digital Modulation Techniques Using Low Cost Components

Abstract

Through this project report we intend to bring about an economical implementation of various digital modulation techniques for a clear demonstration in the communication laboratory. This will bring in a reduction in the expenditure made for the expensive ready-made kits for the manifestation of the various digital modulation techniques. The annual maintenance cost for the various kits will also be removed. This will help the university in an economical manner. This will bring forth each subcomponent apparently to everyone, providing a better knowledge of their individual performances and a feel of the modulation techniques. Also, as all the subcomponents will be distinctly visible it will be quite easier to repair the circuit whenever some defect comes into being. One of the limitations that can be observed with the usage of kits is that a single kit is to be shared by three to four students simultaneously as they are quite expensive. This results as a hindrance in the complete attention that should be paid by every individual student. The circuits which will prove to be quite cheaper than the individual kits, can be implemented and used by every student in an individual manner.
