   Is there any consensus on the neatest circuit to take a noisy push   
   button signal and output a clean rectangular pulse?   
      
   Searching through my ancient (paper) files I found dozens, but my   
   scribbled notes on many show that when tested I'd found lots failed,   
   allowing some noise to reach the output. My starting assumption is a   
   simple CR filter in front of a Schmitt. But before I head for the shed   
   and start bread boarding I'd much appreciate any recommendations please.
