Top ECE Interview Questions :

 

Congratulations on landing an interview call! But Before you get placed in your dream company you have to go through the technical interview. So if you are an ECE ( Electronics and Communication) graduate hoping to get placed in your dream company or get a foot in your dream job then you have to crack some questions.

 

Engineers are expected to have a firm knowledge about their core knowledge or domain. ECE engineers are no different in this respect, As an ECE graduate you are expected to have a firm grasp over core areas such as digital electronics, embedded systems, feedback control systems,  communication networks, control systems etc. So today we are sharing some of the most important questions you can face as an ECE engineering graduate.

 

What is the difference between analog and digital communications?

 

Ans : Analog is basically the procedure of translating audio and video signal ( the human voice) into electronic pulses. digital is breaking the format into binary forms where the video data is represented by series of ‘’1’’s and ‘’0’’s.

 

Distinguish between electrical and electronics .

 

Ans : Though they might sound similar in reality electronics and electrical disciplines are very different. Electronics deal  with DC with a voltage range of -48vDC to +  48vDC, ( example – radio TV Computer PC etc)  whereas electric devices work with line voltage like 120vAC , 240vAC – examples heaters, fridges, incandescent lights etc.

 

What is sampling?

 

Ans : Sampling is basically the procedure of obtaining a set of samples from a continuous function of time.

 

Define a passband?

 

A passband is basically a range of frequencies that can pass through a filter without getting interrupted.
