half wave rectifier,how to build?

[dick dirty]

There's probably an embarrasingly simple answer to this ,but which module or primitive would i need to edit to build
a half or full wave rectifier and how would i accomplish this?I hope the answer is not too humiliating.thanks.

Hi try this

rectifier.osm

its ok for sine and tri waves

[dick dirty]

thanks for an amazingly fast reply ,ill check it out, cheers

I think i messed up,it was supposed to be a half wave rectifier and i dont seem to be able to get it to do this without including the distortion of a full wave rectifier,so forgive me for the imposition but please please please could i get the same thing as a half wave version.

That has both half and full.

But without band-limiting it's going to alias like a sonofabitch.

Not sure I understand
an OSM or screen shot would be a help to show what your trying to achieve

[dick dirty]

How can i remove the full wave aspect,leaving only the half wave.or vice versa? (total noob)

in your osm you have a half wave rectification on the top oscilloscope and full wave on the bottom one.
the osm appears to delivers both simulateously.how can i separate the two?once again total noob and my coding skills are non existent as of thepresent.

Heres the half

rectifier half.osm

But as oddson says its only good to about 2 octaves above middle c then bring on the aliasing

Thanks ,am testing now

Hmm still the same.pretty much what i did with my guesswork methods.Is there a mathematical reason why
it is impossible to simply remove the negative portion of a wave,leaving the positive unchanged?

[Xtinct]

Are you just looking to change the offset so all of the wave is above 0 ?

[dick dirty]

Are you just looking to change the offset so all of the wave is above 0 ?

If that means thateverything blow zero is gone and everything above zero is unchanged,then yes.

[dick dirty]

If that means that everything below zero is gone and everything above zero is completely unchanged ,then yes.

[Xtinct]

No the half rectifier I posted does that
