   I'm glad you showed up. I'm trying to settle an issue in synchronous   
   detection. I have a water sample I am measuring ppm pollution of a species in.   
   I can synchro detect the transmission - that's not a problem. But the signal   
   is way down in the noise.    
   Exactly how can I get it out?
