 Complex Number tutorial 27 28 (1/21/2008 12:48:59 PM) Hi, I have begun a complex number tutorial which shows how e^jwt works. It is located: http://fourier-series.com/fourierseries2/complex_tutorial.html I have more work to do on this, but come take a look. I...bulegoge (388)

 A daft question 14 36 (8/13/2012 8:03:57 AM) but my mind has gone blank! The output of an FIR filter is say s(k) = X'W(k) where X is the input vector and W(k) the weight vector. This is convolving the two vectors X and W to give a scalar s(k) ie the...gyansorova (868)

 ADC SNR testing using tone 17 29 (8/1/2012 8:35:27 AM) I have been looking at SNR of quantisation noise and was impressed by an article titled: Taking the Mystery out of the Infamous Formula, "SNR = 6.02N + 1.76dB," and Why You Should Care by Walt Kester The ...kaz

 Are all farrow filters polyphase filters? 1 24 (8/13/2012 4:31:21 PM) I know what a farrow filter is and I'm familiar with the efficient polyphase implementation, but the structures I've seen in articles about Farrow filters and the structures in the articles about "polyphase" ...colin22

 Sign-extension on ADSP SHARC 21469 ?? 4 58 (8/11/2012 4:32:55 PM) Hi, I have some 24bit audio data (stored in an unsigned int). I have to sign extend it to 32 bit. From what I understand, I just look at bit 23 (counting from bit0) which is the sign-bit. If it is 1 then...mjames2393 (72)

 DC Removal for human voice 18 29 (8/7/2012 1:04:33 PM) Hello, I have an audio file that contains human voice possibly with DC bias. What are the pros and cons of DC removal using high pass filter vs. just computing the average and subtracting from each sample?...Ury

 Sampling Complex Signal 22 25 (8/5/2012 1:38:11 PM) Hi, I know you have to sample above Nyquist or you risk aliases folding into the passband. But it if your signal is complex, it seems to me that in a given interval of time youâ€™ve collected twice the in...Walter
