no more Collins filters

[Richard O'Neill]

  Collins states: "Our filters can achieve bandwidths from 0.05 to 5 
percent."

Are there now better substitutes for analog signals or has the emphasis 
shifted exclusively to digital? Is there no longer a place for analog?
It seems to me that something is always lost in transmutation to 
digital. Sadly, once transmuted, never the twain shall meet.
The 'verse may be governed by rules of quantum physics but on my scale 
and time frame it'll remain analog to me. Like Einstein, I find comfort 
in that.
