if i phase shift a sine wave does it cause spectral leakage?
Hello All, Lets say, N = 32; n = 0 : N-1; fin = 1500 hz; Fs = 48000 hz; % Fs/fin = 32/1 xn = sin(2*pi*fin*n/Fs + theta) xk = fft(xn) If Fs and fin are exact mutiple, if i have theta non-zero, will it cause spectral leakage in FFT mag response, or it will... 4 Aug 2010 10:17

RGB of Audio
Hi., Well, with out wasting your valuable time what the point I want to shoot is that, In an Image for a given pixel we can get its RGB values.I mean consider this small example if the pixel is 24-bit, R = 8 G = 8 B = 8 R, G & B are in the range of 0 - 255. combining these three color valu... 28 Jul 2010 08:31

Opps: DDS Interface
It would help if I used the right abbreviation, DDS for Digital Data System and older telecom data interface similar to T1, but slower, with no framing I believe.

In general, can I use the bandwidth efficiency for particular modulation to calculate the data rate given bandwidth?

Filter and inverse filter =/ timedelay?
Hello, This might be a silly question, but I can't figure out what implications the phase of a transfer function has for causality. If I pass a signal to a filter and pass the output to the inverse filter... my intuition of causality tells me then that the output of the inverse filter can not be the same as what... 26 Jul 2010 16:01

DSS Interface
We happen to be doing an upgrade to an existing card I am selling a customer and they are asking about the feasibility of providing a DSS interface (56 kbps AMI encoding). Their thought was to use the audio I/O which has very strong differential drivers with an output impedance of 50 ohms. We can boost the sample... 26 Jul 2010 10:30

For sale: Freescale Symphony Soundbite dsp kit
[with apologies for cross-posting] Hello all, this has been sitting on a shelf for far too long, virtually unused. I got it a couple of years ago in a rare moment of employedness, with the intention of developing some dsp plugins for ProTools (the dsp is the 56371). Suffice it to say this has not happened, ... 26 Jul 2010 08:19

PolyTune
Hi All, I'm a software engineer and musician who has always been keen on learning more about the meshing of these two fields. I've been studying DSP for personal interest (I've created a couple fun software experiments like synthesizers, drum machines, tuners). I just recently acquired one of these cool PolyTune t... 4 Aug 2010 05:59
