I'm trying to rectify a sine wave from my laptop (generated by a simple oscillator in Reaktor). It's only half-rectifying though. I've tried various things, including a different set of diodes.
Yeah the ground on the jack is the brown one going into the bottom half. I can see how there might be a problem there but can't quite get it.
nobody knows what half-rectifying means. does it mean you're just getting half the pulses, like the red line in the pic?
also, you dont mention how you're seeing the waves. if you're using a scope or a pc-scope then you're probably shorting out one set of diodes when you connect the probes.
Yes the red outline is what I'm getting. Now I'm trying to bias a signal (i.e. put a DC offset on it) and of course that doesn't fucking work either. Nothing I ever try works. The most trivial thing and it just fails.
Funny thing is, I'm looking at the Reaktor screen in the background and reminiscing how simple it was to make signals do what you wanted. Wanna DC offset? Add a constant to it.
Wanna make it bigger? Multiply it by a constant.
I think I might just burn all my electronics stuff and get a tattoo reminding myself that it's never ever gonna happen, so don't ever be tempted to try it again because all it leads to is dismay.
It's because your ground is a ground, and your signal is going positive and negative compared to it. Try connecting the signal to where it is now as well as where the ground is now, then move your ground to the output negative position.
it has to go negative or else it wouldnt sound right. either the output chip is dual rail, or more likely, there's a cap in series with the output which removes the DC component, leaving only beautiful AC.
Here you go faggot.
the diodes on the left are a waste since you connected your bridge all wrong. So you're getting a semi rectifier (loosing the down signal) for full rectification youse this. Pic related.
adding a cap between the + and - will make the rectification a bit more smoother.
>got a few transformers out of a PC power supply
since you ripped a bunch of pc psu why dont you dig up these things (they're full-wave rectifiers in a box) and use it instead of those diodes.
oh and those transformers arent very useful since they are designed specifically for the switching circuit that you pulled them from (unless you wanna break them apart and pull out the copper wire of which there is very little).
Just use built a differential amplifier, this gets rid of the ground as well
Oh wiki images, how i love you.
