MOTM

Could someone provide a brief explanation of these two hypothetical modules,
for those of us who haven't been around long enough to know what they are?

> JH interpolating scanner
> JH-5 style dual LPF

I wish to cast my vote with intelligence. Yes, I could attempt to find this
information by digging through Yahoo's highly annoying archives, but I'm
lazy and often the precise nature of any give module is difficult to discern
from the archives anyway.

Thanks,
