RE: Cap Value

"a subjective call "

Isn't it true that to completely escape the effects of a first order high pass (or low pass) filter the frequency of interest needs to be one decade away from the -3db point?

So for a high pass filter (like a cathode bypass) if the caps is sized for a -3db point of 2Hz then at 20Hz there is no phase shift or amplitude loss?

So at 20Hz and up, wouldn't there be 0Vac across a cap? Unless there is some other "flaw" in the cap?

Thanks.
