Spectrum Analyzer Update – 60 Hz Band Test

Posted by aonomus on July 19, 2008

Well, I received parts today from Digikey and put together my first bandpass filter at 60 Hz, the video outlines just about everything, starting with a brief explanation, test with a song, then test with a frequency generator.

Also, the schematic is mostly done however I’m holding off on releasing it until I find a better way to give this a pre-amp. The LM358 used for a bandpass filter seems to require a heck of input voltage in order to give any output, and likely I would need to preamp each band individually, thus the schematic would get more complicated.

Ok, enough with the wall of text, video time.
