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.

Enjoy!

PS does anyone have a power supply for a Marshall Time Modulator?

Subject: [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.
