| Jul 30, 2013 at 19:00 | comment | added | SAH | @user4619 I don't know much about wavelet. but I have a small background, I know wavelet uses scales. but there is a function in matlab that converts scales to frequency[pseudo]. so i used that function and convert the scales to pseudo freq. | |
| Jul 30, 2013 at 18:51 | comment | added | Tarin Ziyaee | @Electricman A spectrogram is not the same as a scalogram. If you are going a scalogram, there is no frequency VS time, only scale VS time. So which one are you doing exactly? | |
| Jul 30, 2013 at 18:41 | comment | added | SAH | Hi @user4619; Look at first plot. you see a plot[freq-magnitude] on the right side of the wavelet scalogram[which obtained by matlab]. second picture is my wavelet scalogram. but I don't know how to plot[freq-magnitude] like the right side of first plot. any help plz? | |

I am not sure if I understand your question. but if you mean what it looks like, its like the 2nd link which I maintained at the question. and I want a plot like 1st link. (2nd [myplot]) cubeupload.com/im/bSSlMI.jpg 1st[desired]) cubeupload.com/im/KbhGMI.jpg here is my signal <fileswap.com/dl/Lwf7n96fAt/test4.txt.html> here is my Mfile <fileswap.com/dl/gMrslBFAdb/mfile.txt.html> best regards. | |
