Engineering Practical Lab Guides

Laboratory work is fundamental to engineering education, bridging theoretical concepts with hands-on implementation. At Geetha.org.in, we provide comprehensive lab manuals for electronics, electrical, computer science, and mechanical engineering subjects—complete with aims, apparatus lists, circuit diagrams, procedures, observations, sample calculations, and viva questions.

Electronics & Communication Labs

Basic Electronics Lab: Diode characteristics (forward/reverse bias), transistor characteristics (CE, CB, CC configurations), rectifiers (half-wave, full-wave, bridge), filters, clipping and clamping circuits. Includes oscilloscope and multimeter usage tutorials.

Analog Electronics Lab: BJT and FET amplifiers (CE, CC, CS, CD configurations), operational amplifier applications (inverting, non-inverting, summing, difference, integrator, differentiator), oscillators (RC phase shift, Wien bridge, Colpitts, Hartley), active filters.

Digital Electronics Lab: Logic gates verification, combinational circuits (adders, subtractors, multiplexers, decoders, encoders), sequential circuits (flip-flops, counters, shift registers), memory units. Includes IC pin diagrams and timing diagrams.

Communication Lab: AM and FM modulation/demodulation, sampling theorem verification, PCM, TDM, line coding schemes. Spectrum analyzer and signal generator usage.

Electrical Engineering Labs
