[Elecraft] Design Document (was: KDSP2 and KNB2 together)

[Russell Boutell]

Thanks much, Eric. And if I had read page 8 of the design document more 
carefully, I would have understood that better up front :) BTW, that is 
interesting reading if you haven't looked at it yet. There is a link to it 
on the KDSP info page and is a PDF file.

Both the KNB2 analog noise blanker and the noise reduction filter in the 
KDSP2  work very well together. The KNB2 is optimized for pulse type noise 
(from power lines, cars, electric fences etc.) and does an excellent job of 
blanking it before it can get further into the IF chain and cause ringing in 
the crystal filters. The KDSP2 noise reduction does a great job on broad 
band noise like background static and hiss, significantly reducing listening 
fatigue.
