x(n) is given needx(-n+3) so to solve it: first advance the x(n) signal by 3 units(time) then fold 开发者_StackOverflow社区it, or make a reflection of it
Has anybody used the Apple FFT for an iPhone app yet or know where I might find a sample application as to how to use it?I know that Apple has some sample code posted, but I\'m not really sure how to

Well, I will try best not to make it as a \'I just want the code\' question... I\'m recently working on a project which requires some audio signal processing from local music files (e.g. iTunes Libra
I\'ve got code to calculate IIR filter coefficients, but they seem to lead to a really strange output.This is what the data looks like:sampled at 1 KHz with a 7 Hz excitation oscillation on top of it.
I recorded a radio signal into a .wav, I can open it in audacity and see that there is binary data encoded using a开发者_C百科 certain algorithm. Does anyone know of a way to process the signal that i
Given is an array of 320 elements (int16), which represent an audio signal (16-bit LPCM) of 20 ms duration.I am looking for a most simple and very fast method which should decide whether this array co
