Finding the Cutoff Frequency for RL High-Pass/Low-Pass Filters

[Petrucciowns]

Does anyone know the formula to find the cutoff frequency for an RL High-Pass/ Low-Pass Filter?

I know with RC filters it's 1/ (2ΩRC) ,but this does not work for RL filters.

I figured it out, but if anyone is ever looking for it it's:

Fc (Cutoff frequency) = R/ ( 2π L)

Your PI symbol is coming out as an Omega...

FYI, if you copy-and-paste the text on the right below, you'll get a nice looking pi symbol:

π . ← . [noparse]π[/noparse]

That's weird, but it's all fixed. Thanks for pointing it out.
