# Talk:C/4 orthogonal

I know very little about c/4 puffer and rake technology, so if anybody knows anything, please add it and correct any mistakes I made. Also, can anyone confirm whether the p20 block puffer was the first puffer of this speed (I kind of guessed that it was)?

Nope, the first c/4 orthogonal puffer was this p9732 one by Summers (though it was indeed found in Jan. 1999):
