Re: Oscillator issues causing me pain

Let me restate that, not on/off, but a square wave that drops the volume to a certain level, that level being controlled by an "Intensity" setting. Gives a choppier sound.

Re: Oscillator issues causing me pain

Not the one I'm making :) The classic 60 Tremolo was indeed an LFO amplitude modulating the source, newer ones have a hard/soft setting with the hard setting being more of an on/off effect, and the soft the classic sine.

Re: Oscillator issues causing me pain

I don't think I need rail to rail, just enough to switch a 4053 or 4051, if I need higher voltage I'll put a transistor amp stage in. I'm just using it as a control voltage, the key need is independently variable frequency and duty cycle from .5Hz to 20Hz, 0-100%. I got it working last night, but on...

Re: Oscillator issues causing me pain

actually, I don't need the triangle to be rail to rail, I just need to limit my comparator bias range to whatever output the triangle wave puts out (0-4Vdc, it turns out), the comparator puts out the rail to rail control signal I was going for. I just need to add in a couple of resistors, and buy my...

Re: Oscillator issues causing me pain

Woot! Finally got a clean triangle out. Wrong voltage, wrong freq., but a little more shotgunning and I got me my generator! woohoo! Couple extra stages/tweaks to adjust F range and levels, and I'll have my ramp generator to feed the pulse width modulator :grin:

Oscillator issues causing me pain

Hi Everyone! This is my first post here, and I hate to start by begging, but I got a problem. I've gone through my textbooks, looked online, and found nothing that will help. I'm designing a variation on the classic tremolo effect, and want to do it the old school way. Don't ask me why, I like makin...
