Hi,
I'm pretty new to electronics and this is my first time posting here.
I'm looking for some help with a breadboard circuit I'm working on that uses two CMOS 4049 chips to create two oscillators that output via a mini-jack audio socket to a small portable speaker. The idea is two have the output from the chips mix together when they meet at the output, and have two spearate tones whose pitch I can control using potentiometers. Currently to do this I need to use separate 9v batteries for each circuit, as when I use the same power for both, the signals seem to blend into one.
So my question is: how can I use the same 9v battery to power these two CMOS chip circuits without their signals bleeding into each other?
I need something that isolates the power I think.
Here's a pic of a circuit similar to one of the two circuits I have (I don't have a camera here):
Thanks in advance for any help.
Mike
