Digital Data Transmission by Baseband Pulse Amplitude Modulation (PAM)

Aim of the Experiment

In this experiment, you will learn the basics concepts of digital communications like pulse shaping filters, Nyquist criterion, eye diagram, inter-symbol interference and clock recovery. You will learn digital data transmission using baseband pulse amplitude modulation.

Before you start with the experiment, it is necessary that you have an understanding (at some level) of the following concepts:

LabVIEW Implementation: (only for labs prior to fall 2011)

A lab5.vi contains a skeleton for the LabVIEW implementation. You will need to set the "Sample Rate" constant and connect the "Format Eye Diagram" and "Display Eye Diagram" VIs. The part that converts an array to a waveform has already been provided.
