UPDATE: I figured out how to implement these concepts in Gnu Radio (since I cannot program worth anything), and it worked flawlessly. Unfortunately, in Gnu Radio,...
Out of curiosity, how are you handling the +/-pi boundary issue? If one sample falls on one side of the boundary, and the other sample falls on the other side, wouldn't...
Not for implementation, but to answer a question from a student. (Kaz called it when he said, "It is only useful to know that theoretically as part of a lecture."...
So, is that a "Yes, you can, but it's a silly way to do it?"Let me ask the question a different way: Would anyone on this forum implement an IIR filter in the frequency...
Silly question: Is it possible to implement a IIR filter in the frequency domain just as you would a FIR filter? Or is the answer, "Well, you COULD, but that's a...
So there's this rumor that I just made up where she is working on a series of albums that she is sure will be hits. She's just going to number them in order, "One",...
Thank you, James. I understand the concept of analytical signal. I just wanted to ensure that it *only* referred to one without the negative image (as you've discussed...
First, thank you for the reply. I feel as if I've just completed a rite of passage because I understood everything you just said. Second, it sounds as if Slartibartfast's...
Question for the crowd: The definition of an "analytical" signal is a complex signal that only has a positive frequency. Would you still call a signal with only...
You want the difference in the phase angles, and the product of two
phasors multiplies the amplitudes and adds the angles...that's basic
complex arithmetic, there's...
Cool! Thank you!The issue is that, when you do this in the digital domain, the polar form of the math will give you the wrong value if the two samples being used...
Let me see if I can parse out your equation:$$ R \exp \{ j \omega t[0] \} \times R \exp \{ j \omega t [-1] \} = R^2 \exp \{ j \omega \left( t[0] - t[-1] \right)...
i still haven't figured out how to do math on this site.It turns our your code is fine; the only change that @stephaneb made below is he used a double dollar sign...
Thanks for the reply. Does Frerking explicitly mention calculating phase difference between consecutive samples by multiplying one sample with the conjugate of the...
In this case, it is simple. We're looking at this from the point of a FM signal. A digital version represented by complex samples will only have an instantaneous...
Hmmm. I tried your mathjax on the Mathjax.org demo page, and it rendered perfectly. I don't think the problem is your math.Rather than try to make the math work...
