I'm wondering if one of you math wizards might help me. I want to make a simple, basic low pass filter (1 cap and 1 resister) to block any frequencies above about 300 cps. I found some formulas, but I get lost in the capacitive reactance and impedance stuff. I would like to use a low value resistor if possible. Input is about 210 volts @ 200 cps. Any ideas? Even approximate values would help. Thanks for any help you might give me.
Regards,
Doug
