It may be better said that a Noise Blanker responds best to impulses
with a fast rise time like ignition noise from a gasoline engine. It
does not have to be repetitive (but often is).

I have one little nit to pick with this. In a properly designed
blanker, there is no requirement that the noise be repetitive; blanking
should occur on a single pulse or on random pulses. Blanking becomes
ineffective when 1) an undesired signal appears in the detection
bandwidth that exceeds the threshold and triggers the blanker more or
less continuously or 2) the duration of the noise pulse is so long that
intelligibility suffers. Atmospherics fall into this latter category.
See: http://k6mhe.com/n7ws/Noise_Blanker.pdf for more of my opinion on
this. (The missing text in the last paragraph was not my fault.)
