SignalScope Pro / Re: FFT Speed
« on: December 15, 2010, 06:44:14 AM »
Hi, and thanks for responding.
My question was related to computational speed.  I understand the sampling time may be the long pole in the tent, and the computational speed will vary from platform to platform....but was thinking about using the iPhone4 with remote data aquisition equipment to provide it with a faster stream of sample data and processing multiple FFTs per seconds on the streaming data set.  I don't need much time to perform other functions once the FFT is complete, but I'm concerned that the iPhone (of any variety) may not be able to keep up with, say, 10 each 4K or 8K FFTs per second.  Was hoping someone may be able to throw a ballpark number at me. 

Thanks for your great work on this product, by the way.  We're trying to buy a copy of it right now for testin and other uses.

Hello.  I'm new to this forum and was wondering if anyone could point me towards where I may be able to find data on how fast the FFT is performed in SignalScope Pro for the various sample sizes identified?  Would greatly appreciate your help.
