[TenTec] noise blanker

[Ken Brown <ken.d.brown@verizon.net>]

A "noise blanker" is actually a signal blanker triggered by noise. The 
noise that is used to trigger the blanking can come from the same IF 
that the desired signal passes through, usually before the narrow 
filtering in that IF. In some cases the noise pulses that trigger the 
blanking come from a separate receiver, or a separate IF system in the 
same receiver. In all cases (that I know of) the blanking cuts segments 
of the desired signal out (when the noise peaks occur) and is 
necessarily a distortion of the desired signal.
