Saw Multiplier

Postby adamszabo » Fri Dec 11, 2015 9:58 am

Hey guys, I found some interesting info on a cheap way to generate multiple saws from a single saw osc, and I though Id give it a go. The document I used can be found here:

http://electronotes.netfirms.com/EN87Part.PDF

and also some more info here:

http://analoguehaven.com/doepfer/a137-2/

I have attached a version of how far I got. Unfortunately I dont understand all the scientific explanations, I was taking some wild guesses at points. I think I did it correctly, if you move the phase knob you can hear that its like if there are two saw waves, but I guess it should sound like its moving and there should be a couple more. If anyone is interested feel free to mess with my schematic.

Adam, have you noticed the rather severe aliasing? The material you quoted refers to the analog domain. In the digital world all frequencies above Nyquist fold back into the audible band, which may sound nasty since these frequencies are not in tune. I am sure you know all this.
