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...
Thanks, Slartibartfast.
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...
Good morning, everyone! I've been researching the history of digital demodulation, and Rick Lyons passed this thesis paper written by James Shima on to me. In it,...
