10 Questions
- Q1. Explain Fourier Series based on your understanding
- Ans.
Fourier series is a mathematical representation of a periodic function as a sum of sine and cosine functions.
Fourier series is used to analyze and synthesize periodic signals.
It decomposes a periodic function into a sum of sine and cosine functions with different frequencies and amplitudes.
The Fourier coefficients represent the amplitude and phase of each frequency component.
The Fourier series can be used to approximat...
- Q2. If two sine waves of different frequency are added will resultant wave be periodic. If so what is period
- Ans.
Yes, the resultant wave will be periodic with a period equal to the least common multiple of the two frequencies.
The period of the resultant wave is determined by the least common multiple of the two frequencies.
If the frequencies are incommensurable, the resultant wave will not be periodic.
If the frequencies are harmonically related, the resultant wave will have a period equal to the fundamental period of the lower fr...
- Q3. What does odd and even harmonics of fourier series signify
- Ans.
Odd harmonics represent asymmetry in a signal while even harmonics represent symmetry.
Odd harmonics are multiples of the fundamental frequency and have a phase shift of 90 degrees.
Even harmonics are also multiples of the fundamental frequency but have a phase shift of 0 degrees.
Odd harmonics represent the asymmetry in a signal, while even harmonics represent the symmetry.
For example, a square wave has odd harmonics onl...
- Q4. Explain aliasing, nyquist sampling theorem
- Ans.
Aliasing occurs when a signal is sampled at a rate lower than the Nyquist rate, resulting in distorted or incorrect signal representation.
Nyquist sampling theorem states that a signal must be sampled at a rate at least twice its highest frequency component to avoid aliasing.
Aliasing can be avoided by using a low-pass filter to remove high-frequency components before sampling.
Examples of aliasing include the wagon-wheel...
- Q5. If a sine wave is sampled at 1.5 times its original frequency, can the original wave be retained? (Ans: Yes)
- Ans.
Sampling a sine wave at 1.5 times its original frequency retains the original wave.
The original wave can be reconstructed using interpolation techniques.
The Nyquist-Shannon sampling theorem states that a signal can be perfectly reconstructed if it is sampled at twice its highest frequency component.
Sampling at 1.5 times the original frequency satisfies the Nyquist-Shannon sampling theorem.
This technique is used in digi

Interview Preparation Tips
Experience: The test for Analog and digital was conducted online and Signal processing was offline. Analog tested basic LCR circuits , bode plots and analysis of poles and zeroes. Questions on transistors were also asked. 10/20 would be a good score , give that there is a negative mark of 0.5 for every incorrect answer.
Digital was same format as Analog. It tested knowledge on gates, flip flops and Digital circuits using transistors. The exam was quite challenging.
Signal processing mainly tested DSP (Quiz type questions ) . Quite a lot of questions were based on frequency modulation. A sound knowledge of basics should ensure good marks in test. Marking Scheme +1 for correct and -0.25 for incorrect answer. 20 questions, 90 minutes.
A half an hour aptitude based test which was quite simple.
Tips: Ensure sound knowledge on fundamentals of LCR circuits, bode plots, Op-Amps, pole zero analysis and digital circuits. If possible learn basics on biasing of MOSFETs. For signal processing, revision of course work should be sufficient and lay emphasis on basics of frequency and phase modulation.
Duration: 240 minutes
Total Questions: 80
Round: Technical Interview
Experience: Around 10 to 20 people were selected for technical interview.I was shortlisted for Signal Processing and the questions were quite simple than expected. I was asked to explain concept of Fourier series and based on that questions were asked. In the end I was also tested on DTFT basics and nyquist sampling theorem. It went on for half an hour and ended with a puzzle. No questions on resume was asked.
Tips: Be very confident on the basics. Only your basic understanding will be tested. Also during interview make sure you ask enough questions if you don't understand. The interviewer will guide you properly. Remember your approach and understanding of basics concepts will be mainly tested, not formula or answer to the problem.
Round: HR Interview
Experience: Around 4 were shortlisted for HR interview. Selection was based on Technical round performance and Resume. I am not sure if technical exam marks were considered for shortlisting.
Questions were asked about my projects and leadership experience. They asked me if I was into core or leadership profile and that if I applied for ITC , P&G etc ( My answer was NO ). My interest in Electrical Engineering should have a positive opinion about me.I had many good projects in my resume. So I was asked about learning outcome of the important project which I worked on and I was able to answer very well. My personality was also tested which I answered quite satisfactorily.
The round ended after I asked the HR about description of kind of projects an intern will be working on and some questions about profile.In general they didn't consider CGPA as a huge factor for hiring interns.
Tips: Honestly answer the questions faced and whenever you get chance demonstrate your interest in working for a core company. Get your resume reviewed by seniors and highlight appropriate Projects, PORs , skills and coursework.Make sure you are prepared to answer questions based on your projects, PORs and about yourself.
General Tips: In general an interest in core profile and the subject would help in cracking Texas Instruments. Focus on the basics for technical test and interview and highlight appropriate point in your resume. Good luck.
Skill Tips: In general an interest in core profile and the subject would help in cracking Texas Instruments. Focus on the basics for technical test and interview and highlight appropriate point in your resume. Good luck.
Skills: Leadership Skills, Knowledge Of Projects Undertaken, Digital Signal Processing - DSP, Analog Electronics

- Q2. Find the voltage through the resistor
- Ans.
To find the voltage through a resistor, use Ohm's Law: V = I * R
Use Ohm's Law: V = I * R, where V is the voltage, I is the current flowing through the resistor, and R is the resistance of the resistor
If the current flowing through the resistor is 2A and the resistance is 5 ohms, the voltage would be V = 2 * 5 = 10V
Make sure to use the correct units for current (Amps) and resistance (Ohms) to get the voltage in Volts
- Q3. The interviewer just kept on adding an extra resistor in parallel and in series to the resistor and asked me to find the voltage
