In the previous story, how involved in the circumlocution in the wake of ringbark for communication
system and how how much is communications here over the communication system?
Now we're going to see how do and we evolve to a software defined.
Do you and what is the advantage of still communication in the making of the software defined to you?
Before that?
We were discussing this technology is very much helpful in the context of software defined.
So let's start you, your system or everiss, incorporating wireless, receiving electromagnetic waves,
we enable the transfer of information.
So in simple language, we can see using a do, we can receive a signal using remote really of the next
to software defined.
So we have a review and we can control this video using software or we can implement different function
of value in the software than it is called software defined.
Therefore, the software defined radio is the kind of a radio in which all or some of the functions
of regular software defined services in the EU.
There are a function we have seen earlier there was coving.
There was cooling and there was.
It was maybe.
It was maybe it was Morganson.
Modulation, so it depends on us how much information from the outside and we trust to steer.
Turkish software defined radio next on is the best way.
So, yes, there is a range of frequency starting from zero words.
So you can see if you have a signal.
Suppose this was my signal in time and if I brought the frequency spectrum on this one.
So you can see this.
This is start from zero.
This is the frequency domain.
So if you start from zero.
Therefore, the police and the as the.
Frequency near zero hours early.
Speaking, there is no frequency this signal and the value of the signal is the hertz.
Therefore, based on the previous discussion, we can surmise that this is a standard definition, Asgeir
refers to a general article consisting of the Signal A Journal So You Unique Preprogramming added along
with the afternoon, where most of the functions of module's of review system, such as signal generation
modulation, demobilising coding and to manage the nuclear protocols implemented in soffit, there is
waisman.
Whereas in the traditional part of it, the use application, specific integrated circuit that is used
to implement each element.
So if you want to in a generation, then you have to use a different you want to more listen than you
has to.
So what we understand with this idea this year consist of a two part.
One is that it's Tilpa and another is the analog part.
So this is the diagram of Asgeir that is the next year.
So it is the case of baseband processing part that is called the digital domain part where we can generate
a signal modulator signal immortally the signal.
We can do coding and then we can be processing all of and then we have a digital converter DC, which
convert that is there to analog signal.
And then we have the power amplifier so pleased and hit for power amplifier.
Then we got the signal through Antigua.
So this is the ideal architecture which consists of D.C. There is the interface between the registered
domain and the analog domain.
So in the case of an ideal software defined data system, what you want to do, want to move maximum
processing to the near and.
I suppose if we can integrate all those things in the basement, then more good for us, but this is
the scenario of an ideal software defined review.
What happens in the practical domain?
So you can see it is an ideal software defined review to see what that is.
It consists of along with it consists of the receiver.
So you can see here there is a basement part.
So it is called this when processing with all the information of placement and performed in this one
that we have registered and converted, which convert this digital signal to analog signal.
And then we have a power amplifier, then we have an antenna, we have said to switch between signal.
Then the receiver sighed, then we have a low noise amplifiers and we have analog to digital converter.
Then we have again the basement processing, but we have not been able to see a signal and we can process
as what information we required that the desired information in registered domain.
So the first part is called the basement part.
And so during this cold front of the week.
So what you can see is that consist of one is the basement part and second one is the.
And this.
Now, if you want to discuss how impervious to communication system, then we have a different view.
So earlier we have seen this global communication system where we have schools, including gender equality
symbol, more religion in the prosecutors side, in the receiver, including gender equality and symbolic
motivation.
So suppose if you move all these details in the software and you can program this one if these blogs
are programmable.
And in The Oregonian, we have a convergence, we have a power amplifier, we have low noise amplifiers.
Duncan.
And we can do this better because suppose you have as part of the.
And given the frequency of six gigahertz.
By changing some parameters, by changing some parameters, you can trust me.
And again, you want to trust me to gigahertz, you are able to trust me to gigahertz.
So using these parameters, we can do the.
Prosecution frequency, or if you want to do the sampling frequency, suppose my sampling sampling error
is thirty point seven years and they want to change it to sixty one point four for must is then using
this, I can change the sampling frequency of my system.
So a practical SDR, the C would consist of a two part system is ideal.
One is the basement part that was the case of ideals of beauty queen review, and the second one is
the front end.
But the difference is that.
The best part is programmable, be can program according to our needs and the other Frinton, but can
we do Nable so that we can do what you want to do it for next year, the programmable part can be realized.
And so if it's actually the Ninka software defined radio.
So in this topic, we have learned about the software defined radio and building blocks and allowing
the transition from digital communication to the year.
So and the understanded this year consist of Poupart, Gisburne.
And finally, remember these people we lost because they are very much useful.
We will lose most of the time we spend section.
Next, we are going to learn the advantage of the advantage of using software defined using them on
the initial review system.
