Thank you Weiming XIONG for the suggestion.
The tool should now work in newer Matlab versions.

Adding 'find' in 4 lines of flow_tf.m seems fixing it:
line 141~142: innod(find(innod==sym(char(innod(ind)))))=ym_ind;

Thanks for notifying the problem.
For other flowgraph analysis tool users: if you have suggestions on how to fix the problem, please send info to me: marko.neitola(at)gmail.com

Error using symfun>validateArgNames (line 191)
Would you please provide me some help on this issue?

Using the three-parameter fit disables the iterative frequency search. To enable this, use searchflag = 0.
For instance, if you want function messages (verbose), graphics (plotflag) and no iterative search, use
verbose = 1;

The time-domain models presented here was also discussed in my doctoral dissertation, see chapter 6 in:

This model and the related paper (mentioned previously) were also a part of my Ph.D. thesis:

This is actually a cosine fit, I think.

The mismatch noise estimator was improved ad added to submission #29522: "Delta Sigma converter spurious tone predictor".
Both DWA mismatch noise model and DSM quantization noise models can be found in #29522.

I'm quite sure you only need to run it once.

Can anyone suggest me the smtp server for gmail??
where should we include port number in matlab??

Aurelien, thank you for the bug report.
I also noticed that empty mail prefs might cause an error message (fixed).

You should add the value to one in the callback perform_clear_attach as follows :

Here is an example with a regular sinusoid, which may be helpful:

The program worked fine for me it was exactly what I was looking for. I use it for the estimation of the SINAD and subsequent ENOB value. The method tends to shift more signal to the residual when the signal that is used gets longer.

Thank you, Marko! I haven't tried it yet, but this kind of tool is definitely useful!

Thanks Nathan for comments. I guess most people prefer gray background. In the latest version the colors (bg/fg) are easy to customize.
|19 Nov 2009||SendMailGUI Sendmail GUI||Nathan Greco||
Just an aesthetic note: The color is Terrible. Choose something less intrusive...

I made a GUI front-end for this tool. See the link in the acknowledgements-section.

yes its good for me

Very useful tool for everyone working with signal flow graphs. Only thing really missing is the ability to simplify complex analysis results.
|10 Aug 2005||Maciej Borkowski||
Well done. It saves a lot of time, especially when you experiment with different topologies. Thank you!
