In this article, we want to discuss the most frequent and important questions and answers related to Basic Electronics. This article will help you access the best of these questions and answers in the shortest possible time and get the best results in your job interview. So read this article till the end.

Definition of basic electronics

Basic electronics are small electronic components that are part of the electronic equipment used in our daily life. They have different types, including capacitors, diodes, transistors, resistors, and transformers.

In other words, basic electronics can be considered the basic blocks of an industry. These parts start from nano-sized computer chips and range up to large transformers.

Electronic devices that we use daily, such as computers, television controls, and audio recorders are all made of basic electronics and their various parts.
As mentioned earlier, basic electronics have different components including:

• Oscillator
• ICs
• Inductors
• LEDs
• Resistors
• Diodes

This list can be continued, but this is not the main topic of this article, and it goes back to your knowledge in the field of basic electronics.

Top 20 basic electronic interview Q & A 

In this section, we have collected 20 of the most frequent and important questions and answers of the Basic Electronics interview. Remember that these questions are not enough for success in a job interview or a test. You need to master the field and acquire all the necessary skills. Sites like WeTest help you become familiar with remote tests to get ready for the job application procedure.

1) What is the definition of electronics?

Electronics is defined as the study and utilize of the electrical devices that work by controlling the stream of electrons or different charged parts.

2) What is the meaning of “passband”?

Passband is the assortment of frequencies or wavelengths that can pass through a channel without constriction. The passband signals usually have high frequency with specific range of efficiency.

3) Explain the meaning of feedback

You can define feedback as when the outputs of a system back to the input of it. The feedback can be negative and positive, and it’s used to control the system and other parts.

4) Can you provide an example of negative and positive feedback?

An example for positive feedback can be Oscillators and an example for negative feedback can be amplifiers

5) Is there any difference between active and passive components? Explain

Active components need an external source to completely work like a Transistor. Passive components don’t need any external source, like Inductor.

6) How do you define an ideal voltage source?

An ideal voltage source is a device with zero internal resistance.

7) What are different types of communication?

Communication define as exchanging a signal from the transmitter which passes through a medium, at that point the output is gotten at the recipient. Different types of communication can be classified as analog and digital communication. Analog communication takes an audio or video signal and then convert it into electronic pulses, and digital break the signal it gets to binary codes.

8) What is a transistor?

It is a semiconductor that used to control electronic signals and voltage flow. The main two different types of transistors are known as bipolar junction transistors and Field Effect Transistors.

9) Explain the major difference between Latch and Flip-Flo

The main difference is that latches are level triggered, but the flip-flops are edge triggered.

10) What is the meaning of digital system?

It is the system that operates a discrete or a digital system. There are different types of components that build a system, as an example a computer has different parts like a mouse, case, keyboard, etc.

11) What are extrinsic semiconductors?

Semiconductors define as materials that have an electrical conductivity esteem that lies between a cover and a conductor. 

12) What is the definition of an amplifier?

An amplifier is defined as an electronic device that increases the power, current, and voltage of a signal.

13) List the major divisions of power system

Generation, distribution system, and transmission grid.

14) Describe Modulation

Modulation known as the process that different parameters like frequency converts into radio waves. In other words, it transforms baseband signals to passband signals.

15) Can you define Op-Amp?

An Operational Amplifier also known as Op-Amp is an electronic voltage amplifier that is able to boost voltage among two different inputs.

16) What are the usage of Demultiplexer?

A demultiplexer is utilized to attach a single source to different destinations. The most specific use of demultiplexer is that it used in data communication system with error observation.

17) How can you define diode?

A diode is a one-way semiconductor device that has two separate terminals called anode and cathode. This component can allow electronic current to flow in only one direction, known as bias current.

18) Describe the main difference between AM and FM modulation

AM signals are affected by noise because their information is in the signal range, but this is not the case for FM signals because they are in the signal frequency.

19) What is the definition of clipper?

A clipper is a circuit that cuts the voltage higher or lower than a certain limit, which has two modes, which means that the positive clipper cuts the positive half of the signal and the negative clipper cuts the negative half of the signal.

20) What is an Oscillator? Explain

It is called a circuit that makes a wavy output from direct current input and includes 2 models

Harmony and relaxation.

The harmonics are wavy, but not very strong waves

Fluctuations of relaxation are seen in the form of strong waves.

Conclusion

These 20 questions are among the most important and frequent questions along with the detailed answers of the basic electronic interview, which have been compiled and arranged from very reliable sources so that you can get the most effective information about the basic electronic interview questions by reviewing them in the shortest time. So if you want to pass a job interview or want to hire an expert in this field, be sure to use these questions and save your time and energy.
