Communication Engineering laboratory focuses on training the students in both analog and digital transmission/reception of signal. The students here start in the analog area by constructing the circuits of amplitude modulation, frequency modulation and phase modulation. A mini AM transmitter is constructed by them in the MW frequency of electromagnetic spectrum and they do a live transmission with minimum power output. The signals are then received in a pocket AM radio. Learning the concepts, with small applications give them plenty of joy and real motivation towards their studies.
The other important area of analog signal processing is the phase locked loop. Students are given NE 565 PLL IC and made to conduct an experiment to find the capture and lock ranges with their designed specifications. Here the students make use of function generators with frequency sweep facility.
The students are enlighted yet in another area is audio systems, widely used to address the public. The students perform the characteristics of microphone. So they gain knowledge in Acoustical Engineering. They also test condenser, coil and piezo electric transducers used in the audio engineering. In the area of pulse techniques, faculty help them in PAM and PWM experiments. In addition to all the above, the lab consists of the fiber optic trainer, analog signal sampling kit, TDM trainer and microwave testbenches.

In Microwave Lab the students are exposed to the microwave active devices like klystron, gunn diode and passive devices isolator ,circulator,slide screw tunner,magic tee, directional coupler,horn antenna, attenuator, terminations . The students perform all the experiments as prescribed by the university.
The optical communication laboratory is setup to complement the topics studied in the optical communication theory course. The lab is equipped withy fiber optic trainer kits and modules to enable the study of components of an optical communication system.
The students perform experiments to study the characteristics of optical sources (LED & LD) and optical detectors (LD & APD) and optical fibers. Fault detection in a fiber link is studied using the OTDR module. A FSO module enables study of Transmission of optical signal in free space. The lab is equipped with connecterization and splicing kits.
The Digital Signal Processing and VLSI applications are becoming more prevalent in every day use. The field of DSP/VLSI was developed due to the flexibility offered by the use of digital computers in implementing signal processing algorithms and systems. There is a constant need for designing systems with lower power ,higher speed and lower area. The DSP/VLSI lab is equipped with hordes of personal computers. The students enrich their knowledge by using the software tools like matlab,modelsim,Leonardo spectrum,xilinx,HDL Designer Pro and cadence.

Linear Integrated Circuits & Simulation lab is very important for designing the characteristics of OP-AMP,555 Timer IC and to simulate the applications of OP-AMP.It is also used for designing the Electronic circuits-1. Students of various branches design and test their circuits as part of their curriculum. Guidance is provided to the students by a team of expert faculty and lab technicians.The labs are kept open after the college hours to enable the students to engage themselves in designing /testing the circuits in their leisure hours.Students are grouped into small teams and guided to do their mini projects by using the facility mentioned below.
In this electronic world we can't imagine an electronic device without PCB. This lab has been included in curriculum [II Year ECE] for benefit of the students to provide industry oriented training in PCB design, Fabrication, Assembling & Testing.
Printed Circuit Board laboratory focuses on training the students both in Design and Fabrication of PCB. The students enhance their knowledge in various routing techniques, design rules and schematic design. Also the students are trained to create new library for various components. In this lab students are fabricating the given circuit, assembled it and testing has to be done.
The features and facilities available in this lab will help the students to do their projects and enhance their knowledge about the latest trends and technologies in PCBs.
Apart from this we are conducting short term course on PCB design and fabrication for other department students and other college students during the vacation period.
List of Equipments:
Digital Image Processing Lab is committed to building upon its excellent talent and facility bases in order to pursue new applied research and development (R&D) opportunities.
Agreement between theory and experiment leads to knowledge whereas disagreement between the two leads to research that further leads to knowledge. The knowledge accrued through the confluence of theory and experiment becomes an input for a large variety of applications.
Our vision also includes a research component for undergraduate students as well, as we see quality research as the foundation of any academic program.
This lab includes NI Lab View, DAQ Unit and Smart Camera.
It caters the processing of image fundamentals, image enhancement, image restoration, image segmentation, image compression and various image transforms.
