And everyone in this let's assume we're going to implement fire filtering using zoning systems in return
we're going to put this in audio signal to our teacher and your mental response force.
We create a blank modem.
Then mordent first we'll need systems to block every system or down in your system and helps us to our
design into ideal or other form of design flaws.
And then when it is FDA will do is provided by Matlab so we can do it differently just easily we can
create a firestorm of coffee since using this tool will generate a filter.
So then we can use those questions while implementing Astrotrain systems in nature.
Since all of this is the future we're going to generate a lot past.
So we choose a response that looks just doesn't matter we'll be as high or good people it will be minimum
order as possible.
Factor will be as it is and the units we can use normalized our laws will choose us argue that we're
going to use as a sample from a sampling frequency of human hours in under eyes.
This is the sampling of all the artists.
We're going to use the past and we're going to choose a thousand US and the top band will five thousand
homes and magnitude is in and it inched up and now we're getting this design filter button when you
click this you can see the magnitude response on the printer.
There is just design right now.
So this is the response of our filter.
We can export this printer to the Matlab workspace also.
For that we click file export and workspace and it will be exported as he sends and the numerator.
So the variable name will be we'll.
All right.
Any variables that already exist.
If not then we'll export.
So the variable has been export there.
I can see there is this non variable if you DoubleClick we can see that these are different or are confusing.
This is the of convergence of our future we go back to our design
and the sense that the entire design and our block Army us we get this up.
We are by design this FDA tool using this agit we have designed all five filter with Magwitch response.
Now we use this sense in our system jailings system generator block provided by the Xilinx.
So now we take the box out of the door we use.
So the idea that we needed is an old post we need from laju media.
It's not us to select the media file to be used in this morning.
We're going to use this not to select our speech or define it we persist with our filter then really
quite like poor selector slick slick roads or call them or us the data I'm pulled into it.
So the equity or it's one that we're going to use these as two channels.
So it is in a match is one such a process.
This signal we only need one channel and will use them for that we need one channel and we need to unbuffered
this signal.
So we are taken our metrics and we have to convert this matches into a vector jitter vector that will
be converted by unbuffered on before we select the first born.
That means if you select the first of all these artists CNN and these artists you know will be converted
into no major data will provide this sitting on buffer will be as it is we're providing this to the
get it in did we that from Lincoln blocks to the Xilinx block.
This gets really is the interface and it's adding systems and it's a block with the symlink blocks no
means of quide our feature.
So this is the lighted by Xilinx systems that are send in systems in theater and before we can take
this we register with the INS we require registrars we registrars one for our future one opportunity
if free then we can register the entry out
and get we out.
We are getting the composer our just so that is all in the form.
So it's you know it's an offer we can help out or will the spectrum analyzer and also we can go by so
we can see or hear the audio signal after it has been processed by the compiler.
Don't know what's really feature and we can see some Echinus and in some frequency range of that or
a signal for that to be all media media.
Fine.
You mean just five reason that we connect all the blocks we just talk to digital to the filter.
And in this wrister will enable the Enable port so that when he did that will be given them when it
is ready in a half hour or so we give it to someone.
So when the signal is high that drugs are bad we're going to get we out to the buff or come near the
spectrum and find.
Flossed which is the audio file or the file that we're choosing is music fine we will choose audio files
and this or fine we have chosen and it will be samples housing 24 samples parts and all the housing
for channels multi-port we have selected deagle them so that only a single channel has been selected
because this or if I use it to channel fine as you can against the sampling sequences forty four thousand
forty four thousand one hundred homes and get it to be as it is is a fixed point.
We've done 16 bits and 14 by any point we need to change the sample period in frequency of the audio
file.
So it will be one up on what is what was in one and it was all in the genes on the sample.
And this just imagine where to go can we go to the clocking in which is this seeming system to one up
on 44000.
I need is to register it as it is and as we have all the data on the need digging it out and get it
out in this buffer settings the buffer would be causing 24.
It is similar to the 24 that we have and indeed from what you modified as you can see your sample spot
on the channel is given as 2094 samples or channel.
So when we bought that data into the OR is no signal we need to make that thousand twenty four samples
into a single frame that is done by the bar for now at last we have our compiler as we have all these
offices or the low pass filter or using added tool and exported it to the workspace of the Madlib we
can use that variable numb or we can use directly from and then transfer the sense since the compiler
is going to use the tools in the matlab then we can simply use the memo that variable here Indico simple.
It still is you want to take the coefficients from this object radically will use a command that is
ex-MIL after you underscore Muma read or
stroke as well.
So this command read extracts from a few cents and give it to higher compiler and implementors than
the Covisint structure will be involved in type signed.
The quantization will be quantized only constant which can be 16.
Now with this dispositioned fraction and any trips according to the Cosin with it will automatically
certain Arphaxad named for pre-season.
No the full story is ready.
We apply OK now we run this stimulus on time then we can see it.
Spectrum Analyzer let's also see the spectrum of the audio signal that we're giving.
What can you see from this selector
that's similar to this design.
So the spectrum analyzer will suit the output of the street art and the spectrum analyzer one with the
spectrum of deep audio signals that we had in putting this design.
So it is encouraging us to miss them more.
It might take some time for the first one from the second run to do these and more faster.
Smithson is in now as you can see.
So this is the spectrum of the audio file that we have input and this is the spectrum After he doesn't
post this to the compiler.
You can see in the frequency range.
So minus five to five years it gets booed.
Now get him positive side of the spectrum.
You can see that from 0 to fight all those and more close.
It is all of my minutes on the GBM.
But after being processed you can see that only 0 to fight was obviously the magnet students not as
you saw in that video.
Could you find the fine or 5000 Kalulu cycles in host.
You can see the spectrum is aboe minus on it DBMSs So it is hard marked up after that.
These are all in our minds.
One hundred fifty.
So all the frequency components that I was in was has been actually achieved by a larger force than
as we are designing our stranger.
So in such a way we can design a fire feature in this design whereby I don't know passage but we can
also do high pass and pass bans stop and different kinds and design using Stenton system generator and
implementing DSP.
Thank you.
