Whitelion Systems Private Limited HR Trainee Interview Questions and Answers

Q1. Difference between diode and transistor
Ans. 
A diode is a two-terminal electronic component that allows current to flow in one direction only, while a transistor is a three-terminal electronic component that can amplify or switch electronic signals.
• Diode has two terminals, anode and cathode, and allows current to flow in one direction only

• Transistor has three terminals, base, emitter, and collector, and can amplify or switch electronic signals

• Diodes are used in r...read more

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,...read more

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

• FM varies the frequency of the carrier signal based on the input signal

• PM varies the phase of the carrier signal based on the input signal

Q1. What is sampling theorem
Ans. 
Sampling theorem states that a continuous signal can be accurately represented by discrete samples if the sampling rate is at least twice the highest frequency component of the signal.
• Sampling theorem is also known as Nyquist-Shannon sampling theorem.

• It is used in digital signal processing to convert analog signals into digital signals.

• According to the theorem, the sampling rate must be at least twice the frequency of ...read more
