Causal and Non-Causal Systems Better Explained

You must have come across causal and non-causal systems at some point in your Engineering life. Most of us might have simply studied that Causal systems are those systems which respond only to present and past inputs whereas Non-Causal systems can also respond to future inputs. That is correct but there is a lot more to explore about it. In this article we shall discuss the fundamental ideas and philosophies involved in this concept. I am not explaining the mathematics of causal systems here as they are readily found in any related text book and also on the Internet. You may refer to your text books any other source if you do not know what it is. Let us explore more on this.

Substitute Earphones for Microphone in Emergency

Using Earphone as Microphone
Earphone as Microphone
Most of us these days have microphones (mike) available for our desktop computers and it is usually integrated by default for most laptops. But what if we do not have a mike readily available when it is needed badly? It is true that all of us are hackers intuitively. Whenever we do not have something that we need, we try to make use of other available things to get our work done. We shall do the same here.

How to select a Major Project or Final Year Project

I've received a few mails asking for suggestions regarding major project (FYP) selection. So, in this article let me share my opinions on selecting your final year project.
Although most of the discussion in this article is relevant to all engineering students, it may focus more on Electronics and Communications engineering and other local preferences.


Most of you reading this article must have successfully completed your Industry oriented mini-project in third year in engineering and entered your final year.

Your project work plays a great role in and after your engineering life. Not only the marks that you get from your project work but also it will help you understand the essence of what all you have learned throughout your engineering. Also, many core companies emphasize more on your project work than our certificates or aggregate marks. This means that your project work not only fetches you marks but also knowledge, skills and may be a Job too.

Launch Terminal at your Fingertips

Are you a geeky Linux user who works with the Terminal very often? Then this tip is for you. Sometimes when we use the terminal quite frequently along with the other programs, it is not always convenient to launch the terminal or focus the terminal window always. So, is'nt it good if we have a terminal appear and disappear with just a key press?
Did you guess <ctrl>+<alt>+T  ??? No. It just launches a new terminal window every time we use it. But that is not what we usually want and here is an application that does just what we want.

An Easy Way to Turn Off Monitor on Linux and Other Operating Systems With Just a Click

There are many situations when we need to keep our computer running without using monitor. It usually happens when we are downloading any large file or when we are leaving our computer for a short while. In such a case, most of us leave our computer monitor turned ON even though it is not required until the power saving system automatically turns it off after some time. Monitor consumes a significant amount of power. So, turning it off when not in use will save power.


You might be thinking "why not use the button provided to turn off our monitor?"
Yes, you can do that way but not always. It can cause wear and tear and the button may get damaged sometimes as it has happened to me now (esp if you had an old monitor). Also, this button is not provided for most laptops these days. In this article I will tell you an easy solution to turn Off your monitor on Linux.
