Hi!
I have a question regarding a RC-filter I'm trying to create.
I have an amplifier with a microphone connected to power supply in a power bank. The power from the power bank is switching power which causes a lot of noise for my analouge circuit. So I want to filter the high frequencies with a passive RC filter. How do I know which values to use for the resistor and capacitor? And do I connect them right after the power bank but before the amplifyer?
It's a 5 V power bank and my circuit needs at least 2 V.
