Re: [IRCA] [Lowfer] The "Most Important Algorithm Of Our Lifetime"
Hi. Where can I get a copy of this article? When I was taking dsp courses in grad school in the late 70's, some of our exam questions involved writing programs to implement various strange forms of fft algorithms, such as an algorithm for powers of three. Of course, the standard fft algorithm obtains computational speed using arrays of 1024, 2048, etc. I thought the speed of computation had been maximized and analyzed to death, so I'm very interested in this article.
