Hello, I don't want to make a new thread for this, so I'll post it here. I want to do a active band pass filter. The input will be audio from an ipod (about 0,4 V) and I need to bring it up to 3.3 V. Fair enough, I go on a website which calculate resistors value I need for a Bessel filter. Then, I try that on
https://www.dcaclab.com/fr/lab?from_main_page=true
which is a simple app to simulate circuit (I can't understand other circuit simulators) but after I made my circuit, when I probe with the oscilloscope the output is complete garbage. Sorry if this is due to a stupid noobish mistake.
