Typesetting Malayalam using XeTeX

XeTeX is an extension of TeX with built-in support for Unicode and OpenType. In this tutorial, we are going to learn how to typeset Malayalam using XeTeX. With some learning effort, we can produce high quality typesetting using XeTeX.¬†Installing XeTeX XeTeX is packaged for all famous GNU/Linux distros. The installation method depends your distro. For ease of installation and configuration, we suggest to use a TeXLive version 2012 or above – either standalone TeXLive distribution or install from your distribution’s package manager.

A laboratory manual for basic analog communication experiments

I was in need of a manual for introducing the analog communication lab experiments to students who had no prior exposure to electronic circuits or analog communication techniques. Since I found no such book which matched my needs, I planned to prepare a laboratory manual which could help students with the basic understanding of electronic circuit theory to learn and experiment the fundamentals of analog communication techniques. The lab manual discusses different methods of implementing analog modulation and demodulation using transistors, switching IC CD4016, opamp IC 741, PLL IC CD4046, timer IC 555 etc along with passive components like IFTs(Intermediate Frequency Transformers), capacitors and resistors.
