Electronics & Communication Engineering

Semester 1: PCB Design &Fabrication

A PCB is a printed circuit board, also known as a printed wiring board. It is used in electronics to build electronic devices. A PCB serves two purposes in the construction of an electronic device; it is a place to mount the components and it provides the means of electrical connection between the components. Printed circuit board (PCB) design brings your electronic circuits to life in the physical form. Using PCB layout software, the PCB board design process combines component placement and routing to define electrical connectivity on a manufactured circuit board. On the other hand PCB fabrication is the process or procedure that transforms a circuit board design into a physical structure based upon the specifications provided in the design package.

Semester 2: Geometrical Shape Detection and Recognition using Python in Image Processing

‘Geometrical Shape Detection and Recognition using Python in Image Processing’ is a hands-on activity where students learn to utilize Python programming and image processing techniques to detect and recognize geometric shapes in digital images. The activity begins with an introductory session covering fundamental concepts of image processing, including image representation, pixel manipulation, and basic filtering techniques. Students then transition into hands-on exercises, where they explore the OpenCV library and NumPy to implement algorithms for edge detection and contour extraction.

• Evaluation and Testing: Encourage students to evaluate their shape detection and recognition algorithms using test images. Measure metrics such as accuracy, precision, and recall to assess the performance of their models.

Semester 3: DC Power Supply

Power supply is a common reference to the source of electrical power. Most electronic circuits require a DC power supply. The main purpose of DC power supplies is to produce a regulated voltage output for electronic and electric devices. Unlike AC voltage, DC voltage cannot be stepped up or stepped down using a transformer.

Semester 4: IoT Based Systems

The Internet of things (IoT) is the networks use to interface the physical objects. These are the system of interrelated, internet-connected objects those are able to collect and transfer data over a wireless network without human intervention. The different sensors, actuator, software, and other technologies are embedded for the purpose of connecting and exchanging data with other devices and systems over the Internet. This ELC activity focuses on hands-on IoT concepts such as sensing, actuation and communication.

Semester 6: HDL implementation of Digital Clock

Hardware Description Languages (HDLs) are extremely important tools for modern digital designers. Once a student has learned HDL such as VHDL or Verilog, he/she will be able to design complex digital systems with ease and in quicker way. Debugging is also much faster because it requires only the code change. Aim of this ELC activity to design and implement a digital clock (with hours, minutes and seconds) using HDL.
