Problems with the BiQuad Filter design tool
Yes, we're aware of the Biquad filter problem regarding the filter subtype.
There're two solutions: 1) use the work around: before you close the biquad design window, save the configuration to a .xml filter, and everytime you want to change the filter design, load the .xml filter first before doing any changes.
2) use the updated Biquad component with the bug fixed. we're working on a way to distribute this component to all the customers, it may take sometime.
Regarding the second issue, I admit I've seen something similar, but it's hard to reproduce. If you close GDE and do the same thing again, it never happen again. If you could give us a reproducable senario, we could definitely look into this.
are there any updates regarding the BiQuad Filter Design Tool? We are going to provide a TAS based amplifier to our customer for tuning and it would be nice to have the fixed Biquad component.
I haven't heard anything yet, let me ping my boss. Will let you know.
There was no reply to this - I wouldn't mind an answer either, it's been bugging me for over 2 years.
Sorry for the delayed reply.
The patch for Biquad component is now available on the extranet for download:
(this link is no longer available as this product is NRND and we are no longer providing support)
Link seem to be unavailable. Please fix it.
I just checked, both installer and instrution are there, just they appear in a wrong order, please search for the ones dated Jan 25,2012.
Is this available publicly or only to TI employees? If public, please provide a public link.
That link was public, but since TAS3x has been NRND for couple of years now, that extranet was taken down last month, so I am afraid no more access anymore.
