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...

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" ...

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...

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 you’ve collected twice the in...
