In this post I will talk what is cognitive radio and how it works. It is a technology which probably will be used in fifth generation wireless communication system.
Digital counters
This post is the continuation of the post about flip-flops. The counters are a flip-flop sequencial arrangement and it is one of the most important applications of this type of digital circuit.
Arduino tutorial (Part 4, random numbers)
In this forth part of Arduino tutorial, I will show how to use random commands to generate random numbers. One of the applications is to control devices randomly.
