    Dear Students,

    Welcome to the course Communication Engineering (CSE 411). In this COVID-19 situation we all are facing continuous challenges in our life. And we are here together in this pandemic. As the classes will be taken online, we all must come forward for each other. Happy Learning everyone!



    • Instructor Name: A S M Farhan Al Haque

      Designation: Lecturer

    • Course Rationale:

      Communication Engineering may be the fastest growing technologies in our culture today. One of the ramifications of that growth is a dramatic increase in the number of professions where an understanding of these technologies is essential for success and a proportionate increase in the number and types of students taking courses to learn about them



    • Course Objective

      The objective is to enable the students to understand communication engineering in order to familiarize with the concepts of data communications and advanced telephony systems. Also, to assess issues of network security and effective management of data communication networks.


    • Course Outcomes (CO’s):

      CO1
