LTspice tutorial - Ep6 Basics of FFT analysis and .four statment

#19 #ltspice
In this tutorial video I have a look at how the LTspice simulator needs to be set up to perform proper FFT analysis and also how the data can be exported using the .four statement.

this is the best electronics channel, thank you

[vutroslavgandic]

Super clean, fast, reasonable tutorial, why isn't everybody doing it like this.

[RulgertGhostalker]

the guy is really good at what he does, knowledgeable and thorough... this is the best electronics channel, thank you.

Came across your videos a while ago, and must admit you're doing an excellent job with these tutorials. I tried for long time to convince myself to use LTSpice with no effect, and you're the one that made it happen! Thanks a lot!!

[kieranj]

Wow, amazing, well done, I was going to say this is like a toy to you but that doesn't do you or the video justice... it's more like an amazing tool that's complementing your amazing knowledge. Thank you for sharing this and all your other videos to date

the most useful video I've ever seen on youtube!

Beautiful! Very creative!
You thought of everything. I was especially glad that you showed how to increase the resolution of the plot in the frequency domain (increase the simulation time), and that you included a simple circuit so that we could see multiple signals in the FFT plot and a fuller example of the .FOUR command.
I went from knowing zero about distortion analysis using LTSPICE to basic competency in less than an hour. Highly effective and very useful. Thank you for doing this.
I'm going to watch all of your LTSPICE videos.

Really a great tutorial, a must-see for all the students.

Hi...
I've been watching your channel for "somehow" a long time and, obviously, I can only congratulate its (yours) brilliancy, definitely being among the best ones about electronics.

[LuisOrtiz-exkn]

So simple and easy to understand!!! Thank You for the Video!! It really helped!!!

[ReyciclismoMTB]

I had to do some looking around to get it to show both ways on Mac, I really follow your lt spice videos to learn to move around the software. hahaha

[ruenjou]

Straightforward useful tutorial. Good job!

[jindrichvidensky]

Perfect tutorial, thanks and have a nice time

[placiduzzu]

Very precise and concise video. Bravo!

[JurekPrzezdziecki]

You have just opened my eyes :) Thanks a lot

[argg]

What an amazing tutorial - thank you so much!

[ivanm]

Thank you for the great tutorial! Could you explain a little what did you do with amplifier that it stated generate less harmonics? Thanks

[brenocoutinho]

Great tutorial, thank you for your work!

[Jugerzthecat]

Thanks for the video, very helpful! Although what does it mean when your output FFT matches the input almost exactly but is just much higher than the input?

[hugoribeiro]

Very good video! Many thanks! I'll refer this tutorial video in my channel :)
