PSK and QAM

PSK and QAM are the basic modulations. I always get confused when working on these modulations and I have to have GOOGLE opened for reference. While I was googling for this today, I found a good link to a ppt that would explain these from basics with simple waveforms and constellation diagrams.

Good Advice

This was my friend's message and and and it seems to be very true.

LISP Vs C

To implement a task or logic, C needs more lines of code than LISP. As the size of the code increases, it becomes costly to maintain the code. Also "GARBAGE COLLECTION" - a form of memory management, is very efficiently handled in LISP. In simple words, LISP brings with it many attractive features and it takes time to appreciate them.

Many companies are in the process of converting their products to use LISP.
