'[AD] Analog Help'
I need help (not that that's news...)!
My analog skills aren't that great, and I'm working on a project that
is half analog. I've got the basics down, both on the analog and the
digital side, what I need is help interfacing the two, particularly in
making sure that levels and impedance matching is taken care of
properly. The analog side consists of a bunch of op-amps dealing with
audio, and the digital side is a Bluetooth module (with built in ADC
and DAC). I'm just looking for help in the interface between the two
(though advice on improvements on the analog side would be welcome).
This has nothing to do with my motor project by the way, it's related
to the wireless audio thread I had a while back.
I'd prefer to keep the discussions offlist if possible. This is a
personal project, not a commercial one, but my time is a bit crunched,
and I'd like to try to get it worked out quickly. I'm happy to supply
additional details to whomever wants them, just send me an email.
Because I'm looking to have this problem solved for me, not learn how
to do it myself (though I will learn, it just isn't a primary goal), I
realize I should be offering to pay for this service. I don't have
much free money I can throw at this at the moment, but I'm willing to
So if you're interested, please toss me an email offlist and we can
talk about it. Preference will be given to those who have experience
with audio signals and interfacing.
