1. Project Title: HDL Modelling and Verification of MIL STD 1553B Remote Terminal Modules.
2. Place of Execution: ISRO Satellite Centre, Bangalore.
3. Duration: 10 months (August 2014 to June 2015).
4. Objectives: To design the remote terminal used for connecting slaves on to 1553B bus. The 1553 data bus is a dual-redundant, bidirectional, Manchester II encoded data bus with a high bit error reliability.
5. Tools Used: Synopsys VCS (Functional Verification and Post Synthesis Simulation), LEDA (DRC Check), DC (Synthesis) and Primetime (Static Timing Analysis).
6. Conclusion: Understanding and implementation of protocol layer, and verifying the system with a bus functional model coded in Verilog. Lint check to analyse the HDL code for design rule check (DRC) violations. Post synthesis simulation to check for proper timing functionality of the design with respect to setup and hold violations, clock frequency and race hazards.

February 2014 to July 2014

1. Project Title: Design and Simulation of BPSK Digital Modulation Scheme
2. Place of Execution: United Telecoms Limited, Bangalore.
3. Duration: 5 months (February 2014 - July 2014).
4. Objectives: A BPSK Digital Modulation scheme was designed and simulated. Input carrier was a sine wave, input modulating signal was the binary sequence, and the output modulated signal was a binary phase shift keyed signal. A 32 Bit amplitude accumulator was used to generate a 32 bit sine wave with a carrier frequency of 10 KHz and 100101101001 serial binary sequence of 1 KHz frequency.
5. Tools Used: Questasim 6.4c was used for functional verification and simulation. Xilinx ISE Design Suite 14.2 was used for generating a clear RTL Schematic and internal component level diagram.
6. Conclusion: Sine wave oscillator was generated using a Look Up Table (LUT). During the modulation process the information signal modified one or more carrier parameters, leading to shift keying techniques. Design can be optimised so that it can be used for any number of bits as per DAC standards.

September 2013 to February 2014

1. Project Title: Design and Simulation of LCR Bandpass Filters
2. Place of Execution: United Telecoms Limited, Bangalore.
3. Duration: 5 months (September 2013 ? February 2014).
4. Objectives: In this Mini Project the Design and Simulation of LCR filters was done. Basic series and parallel resonant filters were simulated and the effect of resonance on the circuit?s parameters such as current, voltage and impedance were verified. Design equations were derived and verified by simulating the transfer function of typical series and parallel LCR filters. The variation in band width with respect to resistance, inductance and capacitance were simulated and observed with respect to the design considerations. A simple bidirectional narrow bandpass filter was designed and simulated and it formed an effective coupling circuit for Power Line Communication.
5. Tools Used: Matlab M-Script file in the command window to design the system. S Function to compute the transfer function of the control system. Bode Plots and Root Locus programs in order to study the stability of the system.
6. Conclusion: The Coupling Circuit, if properly designed, can equalize terminating impedances on either side for maximum power transfer. Furthermore, these equalized terminating impedances facilitate symmetrical bidirectional band pass transmission.

1. Project Title: Design of a Coupling Circuit for Power Line Communication.
2. Place of Execution: National Aerospace Laboratories (NAL), Bangalore.
3. Duration: 3 months (February 2013 to May 2013).
4. Objectives: In this Project, The Design of an Impedance-Adapting Bidirectional Transformer Coupling Circuit for Low-Voltage Power Line Communications was simulated using Matlab. The functioning of a coupling transformer was also observed, and it was shown that the leakage inductance, together with a series capacitor forms a series resonant band pass filter that can be modelled as a simple LCR circuit.
5. Tools Used: Matlab M-Script file to design the system and Bode Plot, Root Locus programs in order to study the stability of the system.
6. Conclusion: At Low Frequencies though, the Magnetizing Inductance plays an important role in Filtering the Power Waveform.
