I'm still relatively new to this, so this might be a stupid question or I might have some terms wrong.
I've been experimenting with Voltage Controlled Oscillators, mostly CD40106 based.
Let's say I have a circuit with 2 Voltage Controlled Oscillators. One is used as a clock oscillator to drive another IC, and the second is an audio oscillator which will go to an amplifier.
To have an indicator LED for each oscillator, I buffer each oscillator's output and connect each buffered output to an LED and then to ground.
Doing this I have noticed the voltage drop across my Clock oscillator's LED is affects the voltage of the Audio oscillator, which is altering the sound produced in an undesirable way. If I remove the Clock oscillator's LED the interference stops, because the voltage drop is gone.
Is there a way to "isolate" the clock oscillator LED's voltage drop in my circuit so it doesn't affect the audio VCO?
