  • Q1. What is modulation
  • Ans. 

    Modulation is the process of varying a carrier signal's properties, such as amplitude, frequency, or phase, to transmit information.

    • Modulation is used in telecommunications to encode information on a carrier signal.

    • There are different types of modulation, including amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM).

    • Examples of modulation include AM radio broadcasting, FM radio broadcasting,...

  • Q2. Types of modulation
  • Ans. 

    Modulation is the process of varying a carrier signal's properties to transmit information.

    • Types of modulation include amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM)

    • AM varies the amplitude of the carrier signal based on the input signal

  • Answered by AI
  • Q3. Why and which type of transformer do we use to reduce power loss during transmission?
  • Ans. 

    We use step-up transformers to reduce power loss during transmission by increasing voltage and decreasing current.

    • Step-up transformers increase voltage and decrease current, which reduces power loss during transmission.

    • This is because power loss is proportional to the square of the current, so reducing current reduces power loss.

    • For example, power is transmitted over long distances at high voltages (e.g. 500 kV) to red...

  • Answered by AI
  • Q4. Explain Power Factor?
  • Ans. 

    Power factor is the ratio of real power to apparent power in an AC circuit.

    • Power factor is a measure of how efficiently electrical power is being used.

    • It ranges from 0 to 1, with 1 being the most efficient.

    • A low power factor can result in higher energy costs and equipment damage.

    • Capacitors can be used to improve power factor.

    • Power factor is important in industries where large amounts of electrical power are used.

Broke it into financial and non-financial and said ROI seems to be the best metric in financial. Went ahead after getting her buy-in and looked at various cost components in detail like labor, overheads etc. Throughout the interview, I was asked to go deeper and even when I was asked to move horizontally to other cost components, there was no closure of an issue. In the end, was just asked to summarize whatever we had done so far with 2 concluding statements

PI questions
Totally work and CV related cross questioning Why did you do this ELP and what did you learn Why SMC now This was a kind of stress interview where questions would start before I finished my answer. The same tone carried on in the case where scoping questions were frowned upon
Tips: What was good: Cool under pressure, confident What could be better: Take the hint if the interviewer is not giving data and lay out a structure and then ask questions explaining their relevance
