hi,

i am facing problem in generating .WAV file for generating gaussian pulse, the output of the matlab code is for 10ns pulse width and for a time scale of 0 to 20ns with mean 10ns and sigma 5ns, the problem is the wav file which i have generated is time scaling 5 times in tina.

is there any internal scaling factor which i have consider in tina

please help me to resolve this problem

my tina generated gaussian pulse and the output of the audioread wav file are attached below

the wav file is also attached below

Hi Harini,

I opened your .WAV file with MATLAB and it looks like the following:

Here is the matlab file I used to open your .WAV file:

info = audioinfo('inputtyyoo.wav');
[y,Fs] = audioread('inputtyyoo.wav');
t = 0:seconds(1/Fs):seconds(info.Duration);
t = t(1:end-1);
plot(t,y)

I think the process you are using to create your .WAV file might have some issue.

Thanks!

Hi Harini,

That is not something I have too much knowledge about. I think playing around on Matlab might be a great way to get that generated.
I found some great information on this site. www.mathworks.com/.../audiowrite.html

Thanks!
