To enhance precise measurement and observe waveform with better clarity APLAB Digital Storage Oscilloscopes are used. Three MMIC test benches and three microwave test benches are used to conduct experiments in GHz frequency range. Various digital coding and modulation kits are used apart from discrete components to demonstrate the basic concepts involved in digital communication and NI MULTISIM is used to simulate these circuits and verify the results. An OFT kit is used to demonstrate communication and multiplexing through Light waves.
This lab is primarily divided in to Simulation and Emulation. Using MATLAB the DSP operations such as Linear and Circular Convolution, Auto and Cross Correlation, Verification of Sampling Theorem, Computation of FFT and IIR and FIR Digital Filter Design are simulated. These same experiments are emulated using TMS DSK6713 Kits
The Microprocessor 8086 Lab curriculum includes both software and interfacing modules. The objective of the lab with respect to software module is to understand the types of data transfer, to perform arithmetic and logical operations, bit and string manipulation instructions, branch/loop instructions. This is executed by making use of High Level Assembler, Macro Assembler, MASM. Intel 8255 PPI cards used with Intel 8086 to execute interfacing programmes which include Matrix Keyboard interfacing, Seven Segment Display interfacing, Logical Control Interfacing, Stepper motor interfacing etc.
The main objective of the lab is to teach students the method of synthesizing complex digital systems. For this the HDL lab provides full fledged of XILINX design flow using Spartan 3 tools. The students learn two HDL languages VHDL and Verilog HDL. Interfacing Modules such as DAC, Hex Key pad, Calculator, Speed Control of Stepper and DC motors are programmed making use of the interfacing kit.
The VLSI lab provides full fledged of ASIC design flow using Mentor Graphics Tool with 90 & 40nm Technology. Mentor Graphics tool includes software like ModelSim, Xilinx, Leonard Spectrum for front end design; Calibre, IC Flow and AMS Software for backend design.
Some of the ASIC Digital Designs performed are Adders, Multipliers etc. The Code is written in VHDL or Verilog, Simulated, synthesized and verified using Test bench.
Some of the Analog Designs performed are Op-Amp, R-2R DAC etc. All these designs are verified by DC, AC, Transient Analysis and LVS, DRC, ERC are verified. Finally RC extraction and back annotation completes the design verification.
Power Electronics lab is an application of study of the most of the industrial controls at higher power requirements. The lab with is sophisticated equipments are used for the implementation of power electronic units like Choppers, Inverters, Converters, AC Voltage Regulators etc. Power devices like Thyristors, Power UJTs, MOSFETs, IGBTs are used for the realization of these control circuits. Different modules specifically designed to perform the experiments like Analysis of different Power devices, Triggering methods, Commutation Techniques and Speed control methods for various motors are being used.
