so as you know the filter command you have to just design a filter to get the coefficients from that go to matlab and check ''fdatool'' OR ENTER fdatool in ur matlab terminal u will get a gui . from that design ur filter and from export the coefficients to matlab terminal thats it :D
surerly
first u want to do the voice recognition or processing in ur pC
matlab will be good tool to do that
once u have the idea how its work and once u did the simulation further u can implement it in micro controller
@ phongphanp thanks for reply i didnt get u properly what u wana ask ?
i didnt try any thing else
i used FDA tool and get the SOS matrix which correspond to 2nd order IIr filter cascade them with gain to get the 7 order filter.
any suggestion what went wrong will be great help for me. my...
Hi Fvm
it was great help what u told me above
i designed the filter but its not giving proper output to me on system generator.
i attached my file below
if u just see it and suggest what went wrong it will be lot of help.
more over when ever i implemented IIr filter in system gen it...
my filter specification on FDA tool
filter butter worth fs =10000 Fpass = 100 , Fstop =150 and Apass = 1db and Astop =80 db
please can you elaborate more what you wana suggest ?
i cant change anything i just got the specification of filter some one else gonna use it in my department.
hi all
i want to make a digital filter which have sampling frequency 10000 Hz and cutoff frequency is 100 Hz.
I implemented the filter in FDA tool it showing that minimum order of filter required is more than 150 in case of FIR(equiliriple) and i certainly dont wana use that beacuse it will...
k first im planning to store a small size image in block ram by ip core (by loading .coe file). From EDK custom ip i will add that ram. And do some processing
is im thinking rite ? suggest me some link i need guidance i have a year to finish it and im having good knowledge of image processing.
hi all
im doing project on image processing on FPGA ( vertex5 Ml507) . I want to store the image on DDR RAM. I genrated the .coe file. how to do it further i m using EDK and begginer in EDK and VHDL.
once i will store it i want to keep track on pixels in EDK beacuse i want mask. Can any one...
i agree with phongphanp.
last one week im seeing the similar post every one want just code and do the project done, where is learning gone?
@kirjmaru
dont just fined the code it is useless.
for learning matlab just check the tutorials on net u will get thousands of tutorial.
dude it look like if you use any particular band of frequency filter it will block ur audio signal also. so any simple method or direct filtering is not going to help u.
how much time do u have for this? it is not easy task. u need to learn audio processing.
just check Independent component...
do exactly this
[y,fs] = wavread('2'); % there u will get fs which is 22050 in ur case
t= 1:fs;
x3 = y(1:fs);
f =abs(fft(x3));
figure, plot(x3)
figure, plot(t,f)
in time signal small amplitude which are continuous is noise.
I agree with phongphanp.
I listen your wave file today. noise is looks independent of audio you can try independent component analysis to separate out noise and audio but that will be little complex
so try out some filtering methods first that will be easy. If not succeeded than go for ICA.
