ELECTRONICS COMMUNICATION

 

MODEL CIETEC EL 4933c8dfefa92 0

 

OBJECTIVE:

To conduct experiments on analogue and digital communication techniques by log in real time signals through DAQ card to a personal computer and observing outputs on PC scope.

INTRODUCTION:

The LAB ELECTRONICS CIETEC is designed to help the students to understand the basic concepts of Electronics Communication (Analogue and Digital Communication). Students can conduct experiments through a PC. They can learn to log the real time data through DAQ card and outputs can be observed on the PC Scope by connecting CIET trainer to a PC through USB DAQ card.
