hi guys
i study in vienna uni and my cours is control but i recieved one research about Control systems of ring modulator (solutions in different technologies) for example about power consuming.
i need some many refrence
thanks

@judy Hi Judy, I found a very nice PDF that explains the basics of Amplitude Modulation and it contains the formulas behind this type of modulation, I think it maybe will help you: http://www.pa2old.nl/files/am_fundamentals.pdf

Best,
Gilberto

HI gsagostinho
that was great ,thanks alot
but you know i think that i need a excursion about RM
i search since 2 months about controlling RM but i found only explaition of RM
i don't know in which way can i solve my Problem.I'm really nervous
I'm afraid so much from my seminar.
thank god I've found you

Hi Judy,

I don't really understand what you are looking for. You can control amplitude modulation by changing the carrier's frequency and by changing the DC offset (if the DC offset is set to 0, such as the carrier wave oscillates between -1 and 1, then you have ring modulation). These are the only two parameters you control on this type of modulation as far as I know.

Best,
Gilberto

hi Gilberto
it is exactly what I need that you did write
thanks
but i need this explanation whit more exampels. you know when i explain this result in my Seminar i have to prove this result that you wrote for me.
i will really understand what's happend when we chang the carrier's frequncy and DC offset.
my course (discipline) is in German and the subject of Seminar that my Professor gave me is (Ansteuerung von Ringmodulatoren Lösungen in unterschiedlichen Technologien, Kennzahlen (z.B. Leistungsverbrauch,…)) that means :Control of ring modulators solutions in different technologies, metrics (eg power consumption, ...)
and i muss find one way about that
thanks

Remember that this forum can't do your homework. As you said, it is you who must "find one way about that".

However, there are some commercial sites that have online tutors that may help you in understanding these topics. Those sites are more appropiate than a forum.

Have a nice day Farshid

Hi Farshid,

Remember that this forum can't do your homework.

Landon is absolutely correct to point that out. We are happy to help you with problems concerning Pure Data or even electronic music in general, but you seem to be asking for more than that. I gave you all the directions I could, so now it's up to you to continue with your own investigations.

Take care and good luck,
Gilberto

HI Gilberto & LandonPD
they have already understood wrong that they solve my job but I have seen so many website and so many read pdf but I still do not understand how to use ring modulation in the various Technology. therefore took so many examples but however, I am grateful for all.
they have so many helpful
thanks
Farshid

OK, maybe next time we can help you more properly or discuss something. Or maybe you can help us to understand something.

of course

Judy,

The problem is that you are asking something very general, and which the answer probably is in some of those sources we gave to you (Landon and I gave you several links to PDF files, websites and Pure Data patches, all of which deal with this subject).

If you have any concrete question about it, please feel free to post it in this forum, but there is a difference between asking something general like "how do I make a synthesizer in Pd?" and asking something specific "guys, I am trying to make a synthesizer in Pd and I ran into this and that problems and I don't know what's the best way of implementing this or that idea, here is my patch so you can have a look on it, this is what I manage so far, etc".

Take care,
Gilberto

Yes, I'll give you totally right but I am quite a beginner on this subject.
pdf ,all that I've read, they were just the explation of RM.
I thought when I see so many examples, I understand better .but so far they have helped me with understanding.
I thank you for all
Farshid
