Digital, real time audio freq spectrum display
Im trying to build an amp so i can chop it in to different frequencies using a dsPIC to display on a LCD or on a LED matrix.
The amp circuit uses a 56nF mica cap which is hard to find. Its using Microchip MCP6022 dual op-amp. Any ideas what I can use to substitute the 56nF cap ?? Im guessing micas are used to lessen the noise.
Thanks in advance.
Try NPO / COG Ceramic . It should be fine .
Awesome. Thanks a bunch :).
