If my calculations are correct, this would be ~58hz signal? I'd like it to filter out anything above 260hz, so would I need to do this with a microcontroller or can I use a resistor/capacitor combo?
fcutoff = 1/(2πRC)
fcutoff = 1/(2πC) * R
fcutoff * (2πC) = 1/R
fcutoff * 2 * 22/7 * 10uf = 1/R
260 * 2 * 22/7 * .00001 = 1/R
0.016342857 = 1/R
61.1888 = R
If I use 61Ω even, it puts me at 260.804hz
If I use 60Ω even, it puts me at 265.151hz
If the voltage were a square wave as pictured below (which I have not scoped yet) how would the voltage look at 260hz?
