[PD] hardware implementation of [*~]
Hello all, So I'm getting my feet wet in digital circuitry this quarter at my university and I've got numerous projects I want to waste my time on, one of them being a simple ring mod effect in the same vein as the ring mod found here: http://en.flossmanuals.net/PureData/AmplitudeModulation My question is what would be the hardware equivalent of the [*~] object. I guess it don't have to be digital... even an analog equivalent would help me understand it better. Hope this question makes sense, I don't have a good grasp on the terminology in this field one bit.

Re: [PD] hardware implementation of [*~]
You're looking for a balanced modulator. The MC1496 is one. The original ring modulator used a ring of 4 diodes between two transformers. Running two pulse waves into an AND gate will give a binary version.

Re: [PD] hardware implementation of [*~]
You would do well to look here for circuits: http://www.cgs.synth.net/ Note that the circuit that [*~] is like in the context you are suggesting is analogue, not digital. The website above contains a wealth of circuits and component lists. There is also: www.musicfromouterspace.com Enjoy! PS does anyone have a power supply for a Marshall Time Modulator?

Re: [PD] hardware implementation of [*~]
Thanks everybody for the replies, exactly what I was looking for. I am so new to this field of music/electronics that I frequently find myself struggling to grasp fundamental concepts. Googling mc1496 ring mod gave me plenty of circuits to look at, as I'm sure the couple of links you gave me Ed will too. Thanks a bunch.

Re: [PD] hardware implementation of [*~]
You want it to be bipolar for both signal and modulator domains. So that: +1 * +1 = +1 -1 * +1 = -1 +1 * -1 = -1 -1 * -1 = +1 A linear biased transistor and most simple op-amp circuits can't give you this. Hence the need for something like the CA3080 transconductance circuit. If you just need basic ring rod (positive domain only) then a simpler circuit will do On Thu, 3 Feb 2011 17:17:01 -0500 (EST) Mathieu Bouchard ma...@artengine.ca wrote: On Thu, 3 Feb 2011, Tyler Leavitt wrote: My question is what would be the hardware equivalent of the [*~] object.

I built an analog multiplier module out of the AD633. Datasheet has many other mathematical functions. See here: http://macumbista.net/?p=1314 Best, D.
