Interview Questionnaire
10 Questions
- Q1. A transfer function H(Z) in the form of a/b was given. I was asked to implement the block diagram for the given transfer function.
- Ans.
The question asks to implement a block diagram for a given transfer function in the form of a/b.
Identify the numerator and denominator polynomials of the transfer function
Draw blocks for each polynomial term, representing multiplication and addition operations
Connect the blocks according to the transfer function equation
Include any necessary delays or feedback loops
Label the inputs and outputs of the block diagram
- Q2. H(Z)=1/(1-Z^(-1)). Is the system with the given transfer function stable?
- Ans.
No
The system is not stable because the transfer function has a pole at z = 1
A stable system should have all poles inside the unit circle in the z-plane
In this case, the pole at z = 1 lies on the unit circle, making the system marginally stable
- Q3. What does Z^(-1) system represent? (Answer- It's a delay)
- Q4. What are IIR and FIR filters?
- Ans.
IIR and FIR filters are two types of digital filters used in signal processing.
IIR (Infinite Impulse Response) filters use feedback to create a response to an input signal.
FIR (Finite Impulse Response) filters only use feedforward and have a finite duration of response.
IIR filters can be implemented with fewer coefficients but may be less stable than FIR filters.
FIR filters have linear phase response and are generally ...
- Q5. State the sampling Theorem? Is it better to have a the sampling frequency slightly more than twice the bandwidth? Why?
- Ans.
The sampling theorem states that a signal must be sampled at a rate at least twice its bandwidth to avoid aliasing.
The sampling theorem is also known as the Nyquist-Shannon sampling theorem.
Sampling at a rate slightly more than twice the bandwidth ensures that all the information in the signal is captured without distortion.
If the sampling frequency is too low, aliasing can occur, where high-frequency components are in...
- Q6. What is the difference between DTFT and DFT?
- Ans.
DTFT is a continuous function that represents the frequency content of a discrete-time signal, while DFT is a discrete function that represents the frequency content of a finite-length sequence.
DTFT is defined for both finite and infinite-length signals, while DFT is only defined for finite-length sequences.
DTFT is a continuous function in frequency domain, while DFT is a discrete function in frequency domain.
DTFT prov...
- Q7. A sequence x[n] was given. Find y[n] if H(Z)=1-Z^(-4)
- Ans.
The output sequence y[n] can be obtained by convolving the input sequence x[n] with the impulse response h[n] = [1, 0, 0, 0, -1].
The given transfer function H(Z) represents a discrete-time system with a finite impulse response (FIR) filter.
To find y[n], we need to convolve x[n] with the impulse response h[n] = [1, 0, 0, 0, -1].
Convolution can be performed by sliding the impulse response over the input sequence and summ...
- Q8. There is a gun in which 2 consecutive slots of the 6 slots are filled. One of the 6 slots is chosen at random and fired at you. It misses. Choose an option between taking the next slot after the one that missed you and taking another random shot.
- Ans.
It is better to take another random shot.
The probability of hitting the target is higher when taking another random shot.
Taking the next slot after the one that missed you does not increase the chances of hitting the target.
Each slot has an equal probability of being chosen, so the odds are the same for both options.
- Q9. Tell me something about yourself which is not there in the resume?
- Ans.
I am an avid rock climber and have scaled several peaks around the world.
I have been rock climbing for over 10 years
I have climbed peaks in the Himalayas, Andes, and Alps
Rock climbing has taught me perseverance, problem-solving, and teamwork
- Q10. What do your parents do?
- Ans.
My parents are both teachers, my mom teaches English and my dad teaches Math.
Both parents are teachers
Mom teaches English
Dad teaches Math
Interview Preparation Tips
Experience: The test had 4 sections each having 20 questions with +1/-0.5 marking. The timing for each section was Analog: 45 minutes, Digital: 45 minutes Aptitude: 30 minutes and Signal Processing: 60 minutes. I was shortlisted for Signal Processing interview.

- 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
- Q4. He then asked a question on transient analysis ie 2 capacitors connected in series with a switch which closes at t>0 with the voltage across the 2 capacitors being 3 v and asked to find the total voltge
- Q5. Explain the working of a capacitor and resistor and relation between resistance and length , area
- Ans.
Capacitors store electrical energy while resistors limit the flow of current. Resistance is directly proportional to length and inversely proportional to area.
Capacitors store electrical energy by creating an electric field between two conductive plates separated by an insulating material
Resistors limit the flow of current in a circuit by dissipating energy in the form of heat
The resistance of a resistor is directly pr...
