LINUX OS DISTRIBUTION UBUNTU Linux

Linux is an open source OS  distribution .There are many kinds Linux distribution .Such as Ubuntu Debian Fedora Centos etc. In this post I will try to give you a short knowledge about Ubuntu OS distribution. So let’s started here .Ubuntu is an open source Linux distribution. Among all other Linux distributions Ubuntu  is most widely used desktop interface. Mainly Ubuntu consists of three versions the first one is Ubuntu desktop version, the second one is Ubuntu server version and the last one is Ubuntu Notebook remix. Ubuntu has first started its journey on 20th October 2004.    There are many reasons work behind  which makes it more advantageous than windows  some of them are Cost of operation , Built in apps Facility and many more.
UBUNTU VS WINDOWS
 The first point is cost of operation . When ever you need to upgrade your  windows operating system you need to pay money that means you need to buy that version of windows from the  verified supplier. But in Ubuntu Operating system you can   easily upgrade your os with free of cost.


The another point is built in apps facility. In windows interface you need to install office interfaces externally but Ubuntu eliminates this discomfort it has built in office interface which is called LIBRE OFFICE .

3 SCARY MODERN TECHNOLOGY

The operating principal is based on the AUDIO SPOTLIGHT SYSTEM . Holosonic company has developed this technology . It uses tiny speakers to focus sound into a very narrow beam. When the sound goes throw the audio spotlight system’s speaker  it is distorted by the air and make it audible.

2.CYBERWAR:
Can you imagine a war which is performed only by using a computer and you can’t imagine how destructive this war could be. James Comey  the past FBI director have predict that Cyber attacks will soon overtake the place of inter national terrorisom. For example South Korea accused North Korea for cyberattacks.


3. THE TECHNOLOGICAL SINGULARITY:
It brings a revolutionary change in our modern technology . This technology is developed by Vernor Vinge who is professionally  a mathematics professor in San Diego State University.

SUPER HETERODYNE RECEIVER


Today i am going to discuss about super heterodyne receiver . It is an important topics for the students reading communication engineering .Among all of the receivers the super heterodyne receiver is the most popular and largely used receiver.To learn more about super heterodyne receiver at first we have to know the basic definition of receiver.

RECEIVER is an electronic equipment which receives radio signal and convert the information into an useable form.


The working principal of a Super heterodyne receiver can be classified into three different stages. The first section is Radio frequency  section , second section is intermediate frequency section and the third section is audio frequency section.
Block diagram of super heterodyne receiver:

RF SECTION: The first stage is a tuned RF amplifier using two variable tuned circuit. The  two tuned RF circuit form a band pass filter to pass the desired RF signal frequency and blocking the others. This stage acts to boost  the weak signal level from the antenna  above the noise level to provide some signal selectivity. The out put signal from the RF amplifier is fed to one input of the mixer circuit and the local oscillator section to the other.

IF SECTION: The mixer output is fed is fed to two cascade tuned IF amplifier which provides fixed tune and sufficient selectivity to reject adjacent channel signal.


AF SECTION: The output from the IF amplifier chain is fed to the detection circuit where the audio signal is extracted from the if carrier.  The  audio signal is passed through the low pass filter to remove the unwanted high frequency signal. The audio amplifier is one low level audio stage followed by a power amplifier and a speaker.
