Entrepreneurship Development & Venture Creation

listed in the course structure as an alternative to Open Elective-I, but the source syllabus PDF does not contain a unit-wise syllabus for this course anywhere in its 186 pages, so no unit breakdown can be given honestly here.

Power Electronics Lab

hands-on experiments that verify the device characteristics and converter behaviour covered in the Power Electronics course, from firing circuits to inverter control.

• Characteristics of SCR, Power MOSFET and IGBT, and firing circuit design (R, RC, UJT)
• Single-phase and three-phase converter performance with resistive and inductive loads, including dual converters and cycloconverters
• Buck/boost converter operation, and single-phase/three-phase inverter control (square wave and PWM)

Analog and Digital Circuits Lab

combines analog circuit experiments (clippers, oscillators, op-amp applications) with digital circuit realization (adders, counters, registers) to reinforce both electronics courses on the bench.

• Clipper/clamper circuits, transistor biasing, feedback amplifiers and oscillators
• Op-amp based integrator/differentiator circuits, multivibrators using IC 555, and PLL/ADC-DAC circuits
• Digital circuit realization — adders/subtractors, decoders, multiplexers, flip-flops, shift registers and counters

Soft Skills

a skill-enhancement course on communication, self-management and interview readiness aimed at making engineering graduates workplace-ready beyond their technical training.

• Unit 1: Analytical thinking, listening skills and verbal/non-verbal communication
• Unit 2: Self-management — anger, stress and time management, and professional etiquette

Tinkering Lab

a hands-on prototyping lab where students build small electronics and IoT projects to develop practical problem-solving and innovation skills that complement classroom theory.

• 3D-printing design projects and a live soil-moisture monitoring dashboard project

Evaluation of Community Service Internship

the course structure lists this as a 2-credit internship evaluation component with no lecture hours; the source PDF does not provide a unit-wise syllabus for it since it is assessed on the student’s actual internship placement rather than classroom content.
