Linux (Ubuntu)

This tutorial is on Linux (Ubuntu Distro)



Those who already knows about the CLI (Command Line Interface) this tutorial is not for you. I'm going to show you one task each post to perform in CLI(using the terminal).
At first open the terminal by going  Applications > Accessories > Terminal
Then you will see a graphical interface as below:

Now our today's task is to know your current directory and go to other directories
$ pwd : this is the code for knowing your current directory. When you write and press enter, you will see the path of you current directory in the next line.

$ cd 'directory path' : that's the format of the code to change the current directory using command line. In the place of directory path you have to put your desired path(where you want to move)
example: $cd Public

That's enough for now. Later I'll move a little fast. Till than if you have any problem let me know and have fun ;)

PSpice (Introductory) Part - 1

This post is for introducing all with the power of PSpice. Those who already know about this software please wait, I'll write all the steps of analyzing a circuit with PSpice very soon. But now it's for the beginners :D

What is SPICE?  
Before knowing about PSpice we've to know what's SPICE. SPICE is a powerful general purpose analog and mixed-mode circuit simulator. This is used to verify circuit designs and to predict the circuit's behavior in real life.

PSpice:
PSpice is a PC version of SPICE [ Available from the OrCAD Corp. ] . A Student version(which has some limitations) comes with various textbooks.

PSpice can do several types of circuit analysis. Some important ones are given below:

• DC circuit Analysis and Kirchhoff's Laws
• AC circuit Analysis
• Transient Circuits and Laplace Transforms 
• Transfer Functions and System Parameters 
• Series and Parallel-tuned Resonance
• Semiconductor devices and Characteristics
• Operational Amplifier Characteristics

I think this is enough for now. I'll post more about PSpice in the next post with the procedure how to plot circuits on it and Simulation ofcourse!

Till then have a nice time :)
