Not really DSP, but I thought that some of the HAM guys on this forum may have seen this before.Have you every noticed when lighting strikes it causes the RF signal...

Hello,I would like to understand the process of 'near IQ' sampling. I might be using incorrect terminology (so please correct me if this is true) but the idea of...

Hi Kaz,Thanks for your post. Your code does make sense.I have found that most of my problems are orbiting my lack of understanding of the Matlab functions freqz()...

Hello,Thank you very much for your reply. That is an interesting Matlab script.However, (and please correct me if I am wrong here) but the code that you showed is...

Do my questions make sense?With my Matlab code, I've noticed that my plots change a lot if I change the precision of f. f=-10:1:10 produces very different plots...

Hello,
I am attempting to plot the result X(f) for various sampling frequencies. I am adjusting the sampling frequencies to intentionally cause aliasing to see...

Sorry, it might be helpful if I include the book answers :pBut ya, as best as I can tell, I don't think I am dropping any signs or missing any 'i' complex values.Also,...

So I worked out the problem using some of the tricks that you shared and this is what I got ( I did read over your blogs, they were helpful :)This answer is not...
