Additional equipment is also available to enhance the research area for both faculty members and students in the department.
This laboratory has state-of-the-art electronic equipment including Industry-standard Digital Oscilloscopes and Signal Generators. This lab aims at making the students learn about Linear Integrated Circuit (LIC) design, the 555 Timer, Analog communication systems, Logic designing and implementing them using hardware. Linear Integrated Circuits lab provides facilities to design oscillators, amplifiers, filters using operational amplifiers. LIC lab provides students with a simulative environment to analyze the working of PLL and use PLL as frequency multiplier. Also students can design DC power supply using ICs and they can analyze the performance of oscillators and multivibrators using SPICE.
Microwave devices are fundamental to many modem electronic systems, including digital wireless communications. The Microwave section helps students acquire familiarization in Characteristics of Reflex Klystron, Gunn diode Oscillator, VSWR measurements, Frequency and Wavelength Measurement, Study of Power Distribution of Directional Coupler, E-Plane Tee, H-Plane Tee, Magic Tee, Isolator, Circulator, Attenuation and Power Measurement, Radiation Pattern of various antennae.The Optical section aids students in the familiarization in characteristics of LED, LASER, PIN diode and Measurement of various losses, Attenuation, WDM and Data communication using fibers.
Advanced features and techniques of VLSI design provides students with the necessary training to develop complex VLSI systems and enables them to improve their designs by using the tools available in the laboratory. Labs provide hands-on experience with the development, verification, debugging and simulation of a VLSI System.
The students carry out various experiments related to signal processing in the Digital Signal Processing Lab. It has 40 systems with LAN and internet connectivity. All the systems are loaded with MATLAB software package. There are 15 TMS processor kits used in assembly coding related to signal processing experiments.
The main aim of this lab is to impart the knowledge of programming skills by using MASM software for microprocessors and microcontrollers. This lab is used to study and execute various programs like arithmetic operations, code conversions, searching and sorting algorithms using microprocessor kits like 8085, 8086 and microcontroller kit 8051. Interfacing of microprocessor and microcontroller to various peripheral devices to perform A/D and D/A conversions, Displays, Digital clock are also studied and executed. This Lab is enhanced with interfacing boards such as 8279, 8255, 8251, 8253, ADC, DAC, stepper motor, DC Motor, Printer, seven segment display and traffic light controller.
Network Lab allows the students to learn to communicate between two desktop computers and to acquire knowledge about computer network technologies, network equipment, network design principles, configuration and troubleshooting tasks.This lab is used to study and execute various techniques like Error Detection / Error Correction, High Level Data Link Control and Study of Socket Programming and Client – Server mode and Socket Program for Echo/Ping/Talk commands. This lab is also equipped to analyse the performance of network with CSMA/CA protocol and compare with CSMA/CD protocols and Network Topology – Star, Bus and Ring. It also helps to implement the various algorithms like distance vector routing algorithm, Link state routing algorithm and Congestion Control Algorithms using Network simulator; learning about Encryption and decryption is also facilitated
The students work with basic components and equipment. The students also design and test various circuits using theorems studied in circuit theory and principles of basic electronics. The students in turn avail the hands-on experience with all the electronic equipment’s like CRO and function.
Electrical Engineering Lab is used to expose the student knowledge and skills in operating and analyzing the performance of DC generators, DC Motors, Alternators, Synchronous motors, Induction Motors, Special Motors, and Transformers. The Electrical lab covers practical experiments on transformers – open circuit, and compound DC machines, induction machines, no-load and load tests, operation of single-phase induction motors and operation of a synchronous machine connected to a large external source. By performing experiments on these electrical machines, the practical knowledge of the students gets enhanced and help them in their industrial career.
