How to derive Frequency Response using only time-domain input/output samples
sparafucile17 - 2009-03-24 14:31:00
The basic question is how would I know the Frequency Reponse of a "black
box" system if all I had was the inputs going in and output samples coming
out? I know I could use convolution to get a best...
How to add two add two correlated signals, but NOT have comb filtering...

I have two audio signals that are correlated but one of them is a delayed
version of the first signal (let say by 10ms). Now I want to sum them
together, but of course, this produces a nasty comb fil...Re: Best way to getting a high data rate (300Mbps) from multiple ADCs to memory

sparafucile17 - 2008-05-20 14:12:00
I'm close to an answer on this topic, but there is something I'm missing.
I have found the following equation in a textbook for determining the phase
response of a second-order circuit:
PHI(w) =...Re: How DSP folks are affected by the ongoing recession?

sparafucile17 - 2008-04-10 12:37:00
I don't know how best to describe the type of filter design I'm looking for
but I'll try my best: I'm looking for a way to design a "roughly" flat
magnitude response with a phase response that I defi...Re: crackling sound after FIR filtration

sparafucile17 - 2008-02-20 16:45:00
Does anyone have experience with decoding DTS material from a CD or .wav?
I have 2 sources at my desk that output DTS material through SPDIF but the
receiver is flagging them both as PCM!!!
When l...Re: is this design feasible??
