Good idea, let's see how we'd do that.  We'd need something that blocked DC
but let other stuff thru.  Of course we have to block some things close to
DC, since otherwise we'd have to wait forever for the signal to stabalize.
Ooh, ooh, I know.  We want one of them there low frequency blocking
thingies.  I think the fancy name is "filter".  Let's use that so others
think we're more smarterer.  "Low frequency blocking filter" is kindof
cumbersome to say, so let's flip it around and call it a "high frequency
pass-thru filter".  That's still kindof a mouthful.  How about "high
frequency pass filter", or maybe even just "high pass filter".  Oh right,
that's what I said in the first place.  Gee, who'd have thought!?
