Very helpful on the 4quadrant multiplier. I almost understand it now.

[@FrapTools]

It is not a simple topic but we're glad if the video helped a bit!

[@BoardgameBaker]

Love these videos!

Now we are getting into some deep, beautiful waters with these Frap Talks videos, yummy!

Thanks for the positive comments, Chris!

Nice!!

[@FrapTools]

Thank you!

Question: When ring-modulating an audio signal with an LFO, are there still sidebands created (below the audible range)? I guess yes but what says an expert?

[@PspiralifeTutorials]

Im just recently beginning to use ring modulators which I had overlooked for many many years. I am wondering if the 4QM in fallistri and Brenso are analog in design, or if they are digital, or a combination of both. Thanks

[@FrapTools]

Yes, they are both analog!

@@FrapTools I was being silly ^__^ I bought a Brenso and a Falistri... should be here in a few days

@@Starshine777 What a couple! We wish you a satisfying exploration time once they'll be there, then!
