I know there must be an easier way to do a full wave rectifier with standard parts, so far the simplest one i came up with has 1 inverter, and 3 mix2's, and 2 values. it is too wastefull of DSP to use polyphonically.

hi defex,
must be my english, but i have no idea what a wave rectifier suppose to do (does it "rectify the wav"? what does that mean
may be a few explanations of the functions you wanted to achieve can help developper with local knowledge to help

It will take the negative part of the signal, and make it positive so a trinagle wave would change from ^v^v^v to ^^^^^ (nice text art..not:o)

weew
not sure it is possible like this (trying to figure out how to do it but it wouldn't work or be useful with simply inverters etc...) got to find a way to annul what has top be removed from the ^^^^^part (ie remove it before on both the normal and inverted signal....?).
well, i can't help here.

Hi,
this rectifier thing could be easily done
in sharc assembler, you simply have to set
all incoming values, which have a negative sign, to a positive sign. But for what do you need it ?? I could make this dsp module for you !

well it is a good and cheapo way to add 2nd harmonic distortion to a signal, I use it as part of a waveshaper circuit. It would be really cool if you made one!
DSPdev already has one, but then you have to download and install their whole library.

Hi,
i have the rectifier module ready. Contact me if you want to have it, or tell me where i should send it! (my address: steckenleiter@t-online.de)
See ya
