Knowing more on how to get "true" FFT

I have an unexplored area in LTSpice, I have seen a significant different between the FFT responses (for the waveforms generated for the same circuit parameters) for different settings of "Stop Time" and "Minimum Time step" in the "Edit Simulation Command" window. I just briefly went through the table of contents of the book (thanks for the link) and see that there is a chapter10 and sections 10.11.1, 2, 3 describes this. But rest of the book is not that interesting to me as it looks more like a manual to me. Does anyone have any article explaining what should be the optimum settings to get a more real FFT picture? Also, is there not an e-book version released?

Good info, can use good sources of LTspice tutorials. A word of caution on the yahoo group, while most are helpful, one of the members is known to be very aggressively disparaging towards newbies.

You're right, of course. But some will find it handy to have everything needed in one place.

Here are a few links to tutorials and other LTspice references:

The Yahoo LTspice group has nearly 45,000 members and is very active - http:tech.groups.yahoo.com/group/LTspice. You'll need a Yahoo email address and will have to go through the "joining" process.

A good reference and tutorial site is the LTwiki site - http://ltwiki.org

Linear Technology applications engineer, Steve Knudtsen, has a very nice tutorial slide set given to the Denver Power Electronics chapter of the IEEE in 2009 - http://www.denverpels.org/Downloads/Denver_PELS_20090519_Knudtsen_LTSpice_Intro.pdf

Dr. Tony Richardson, of the University of Evansville, has a collection of tutorials for LTspice - http://csserver.evansville.edu/~richardson/courses/Tutorials/LTspiceIV/index.html

Google for some excellent and free tutorial material on LTSpice. 

I'm sure the Wurth book is great, but $50 is a lot for the hobbyist or student when there are many excellent treatments available free.

LATEST ARCHIVED BROADCAST
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
