Talk:Digital signal processor

First implementations of DSP chips was likely military applications, specifically, radar signal processing for fire control radars on USAF fighter jets. Range data was processed to provide targeting information to air-to-air missiles.

"Was likely"? Can you provide sources for this? Note that radar range data can be extracted with analogue electronics (sample-and-hold, boxcars etd), it is hard to see what processing would require a DSP. Passive hydrophone data processing, on the other hand, requiers DSPs for real time beamforming and specrum analysis, seems more credible as an early military application. A submarine or sea going vessel has less of the space, power and cooling constraints found in fighter jet.
