Hi all, I have a 100 KHz square wave and I'd like to utilise a low pass filter to filter out all the harmonics and leave just the fundamental. Leaving me with a 100 KHz sinusoid.
A fourth order Butterworth looks ideal for this but I'm struggling with the maths. Please can somebody show me how to calculate the capacitor/resistor values?
Thanks for any help!![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
