12 db low pass filter
This is a simple low pass filter, using 2 standard npn transistor.
This filter can works also at 5 volt and it's good for microporecessor based project.
The filter can self oscillate and it's a proget I've made with Peppo at L.E.P. laboratory in Milano.
Let me know if you made some modification.

Wow. Simple design. One question: Why are there two 100K cut off pots?
RispondiEliminaSame question ! Should it be done with a "stereo" 100K Pot ?
RispondiEliminayes it's stereo 100k pot.
