Steve is quite right, they almost always introduce artifacts of their own. 
How well they work or if they even work at all depends on the type of noise 
you're trying to get rid of.  i've had instances with power line noise where 
the K3 noise blanker eliminates it completely.  I've had other noises it 
barely touched.  Often it's a question of finding the best compromise 
between reduced noise and introduced distortion.  lou
