Hi all!
This is my first post here and I am looking for directions and will appreciate any pointers and or tips derived from your experience.
I'm currently working on a VCO for an audio application (I am a sound engineer and just finished a course on radio and amplification) however I do have some questions that I'd like some help with.
I designed a VCO using what it seems to be a typical op-amp configuration for this application (image attached).
With some tweaks and experimenting I've got a nice sounding square wave output. As I have experience with other oscillators, I kind of like how they sound with PWM. After perusing some schematics and looking at other VCOs I have concluded that, in order to add a PWM function to my oscillator, what I'd have to do is:
1) Breadboard a similar VCO to the one I've built.
2) Combine their outputs with an op amp in a comparator configuration.
Am I correct?
Am I complicating things?
This is a learning exercise for me and I am trying to challenge my current abilities so I can improve, however I thought it might be of benefit to seek some guidance here.
Thanks in advance!
Emmanuel.
