Welcome to this nootropics Super Tuesday in architecture, under the module to the super decadent architecture
is also known as the eye of convergent architecture.
So it's a second name is I've can what I have is the intermediate frequency.
So you can see here again that architecture consists of a two part.
That is the distal part.
And the second one is the analog part.
So let's start one by one in DSB.
We have in the in the basement section, we have a DSP, FPGA or we can use the GPU.
Also, we will discuss this in detail.
So here we have a bit symbol modulation and other encryption encoding algorithm after work.
Then we have the Irenka part of a complex signal data which which is converted to the analog domain
using digital to analog converter.
We have ideato here and then a to because we have a data here in the analog domain after to be filtered
in a spurious signal present using the low pass filter.
Suppose this is the actual signal and we have some experience here.
So we filter out digits, we use interlopers filter.
So the same signal, same operation is performed in the eye part in the Kuper part afterward.
What we do, we convert it to a certain frequency as the Olufsen.
So elevon is the local oscillator that is used to convert it to high frequency operation or some at
a particular frequency operation.
This is again, according to our moderator, what we see in the previous lecture.
So this is also called arriviste is that it's called a live stage that is also known as intermediate
frequency stage.
So, again, we as we as we have seen previous sort of frequency.
Miksad So we have the positive component here.
We have the so we have to put the some of these frequencies and we have also the difference of these
frequencies.
So since we are retransmissions, we are transmitting the signal very quiet converter operation.
Therefore a band pass filter is used after the after the combination of the NQ signal.
Then we have the second level of conversion using the local second local oscillator.
Suppose that a local frequency is f a low one and F and a lot of frequencies F a two.
So what happened using the F one?
If my signal is that baseband then I will translate it to some frequency that is about to have a little
one plus.
The previous frequency afterward, I will translate into another frequency that is have a lot to again
say we have, but we have a conversation down conversion auctioneer.
So we are again using a band pass filter to filter out the desired signal of interest from here.
Then we passed it through a power amplifier to boost the power of the signal and then it is transmitted
through the antenna.
So in summary, what we can say the RF frequency have RF is a combination of two frequency.
That is F one plus F Halo two.
So this is a conversion that is called intermediate frequency.
And this is this is akin to frequency conversion.
So therefore we are using an for station intermediate frequency station.
It is also called the idea of conversion architecture, or sometimes it also called the dual conversion
architecture, because we are converting to Tannishtha the frequency or if you can see we are converting
to times using the higher frequency and this one is the relative frequency.
And the receiver receivers signal that they are using a Rolls-Royce amplifier.
So the low noise amplifiers is used to increase the sensitivity of the received signal.
Then a band pass filter is used which help us to which help us to choose the desired band after signal.
Then we have our inverse operationalised of this one.
So we use a down converter in the same exact issues can be used as a down converter.
It says a positive side, a converted signal as well as integer.
Don't convert that signal then.
Then we will select that down converted path using a band pass filter.
Then we do the quadrature demotivation and same process in the transmitter site we receive over the
IEEE and signal, which is further sent to the pacemen part and it can be further processed.
So now we have the transponder signal.
We have we have the receiver signal in the basement and we can do a lot of analysis, we can calculate
a different parameter, etc. using these two part of the signals.
So what we can say, suppose let's try to understand with this example.
Suppose the low frequencies here, 70 megahertz and a lot of frequencies here, two gigahertz.
So what we have we have a two stage conversion support.
This is my full signal here.
So first, what happened in this stage one 11.
So we have a fun plus F.
Hello.
So this is my first stage conversion in the second stage conversion.
We have another frequency support.
This is my second stage conversion.
Then we have one plus one plus two.
Again, as we know how the output of the mixer consists of what the frequencies that is F one plus F
hello.
And the one minus F alone.
But since you are the transmitter, we are going to choose this positive.
So.
So this is my total output and the transmitter section.
Similarly in the receiver section, the same operation can be performed and the signal can be received.
So what we have to remember here, what is my preferred, that is the sum of a one plus folo to some
of the local Tovan and so on, the local oscillator to frequency.
In this topic, we have learned about the super Cuban architecture and why it is called dual convergent
architecture due to the availability of the two local oscillator.
And next, we're going to learn one day.
