Filter Testing and Options
I'm getting closer to finishing but there's still one functional block that I'd not yet tested and it's my active filter. Again, a big hat's off to Lior for the inspiration behind my build, but I have done some things my own way.
For example I used a Sallen-Key low pass active filter to get a 1.5kHz Low Pass Filter.
Thanks to the internet, rather than hand crank the numbers, I used this on-line calculator from OKAWA Electric Design. From that design I whipped up this LT-Spice File.
