Links to some useful software are given below. Most of these software are free. Engineering students should find these software useful.
A free PDF converting software is doPDF. It works as a virtual printer and can convert any type of readable files (Word file, Excel file, PowerPoint file etc.) to PDF. The software is completely free. It doesn't leave any watermarks on the PDF like some other softwares. It can embed fonts as well. The software can be downloaded from the following website: http://www.dopdf.com/
STDU Viewer is a free viewer for multiple file formats. The goal of this software is to replace the multiple document viewers with a single one simple application. STDU Viewer supports TIFF, PDF, DjVu, XPS, JBIG2, WWF document formats. These are the most popular formats for scientific and technical documentation. The software is most useful for reading DjVu files, as good software for reading that format is rare. The software can be downloaded from the following website: http://www.stdutility.com/stduviewer.html
Graph plotting software:
Graph is an open source application used to draw mathematical graphs in a coordinate system. The program makes it very easy to visualize a function and paste it into another program. It is also possible to do some mathematical calculations on the functions. It can be used to plot data points. A basic curve fitting option is also incorporated. The graph can be exported to image files (emf, png, bmp etc.). The software can be downloaded from the following website: http://www.padowan.dk/graph/Download.php
Circuit drawing software:
TinyCAD is an open source schematic capture program for MS Windows. It can beused to produce professional circuit diagrams and export net list information to PCB applications. It's large library contains symbols of most circuit elements. The software can be downloaded from the following website: http://sourceforge.net/apps/mediawiki/tinycad/index.php?title=TinyCAD
Circuit simulation software:
LTspice IV is a high performance SPICE simulator. Macro Models for 80% of Linear Technology's switching regulators, over 200 op amp models, as well as resistors, transistors, MOSFET models and 555 timers can be simulated using the free download version of LTSpice IV. The software can be downloaded from the following website:
