## RF loss during lighting strike

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...

## 'near IQ' sampling

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...

## Re: Matlab, properly using IFFT, FIR Filter Desing

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()...

## Re: Matlab, properly using IFFT, FIR Filter Desing

That makes sense. Thank you for your help.Just out of curiosity, what University do you teach at?

## Re: Matlab, properly using IFFT, FIR Filter Desing

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...

## Re: Matlab, properly using IFFT, FIR Filter Desing

Here is my Matlab Code to help explain what is going on (note, the bottom plots in windowed). The goal is that the top plot should be nearly identical to the bottom...

## Matlab, properly using IFFT, FIR Filter Desing

Hello,There is probably an easier way to do this, but I am getting stuck on trying to determine the following FIR filter design.Let's suppose that I have a transfer...

## Re: DTFT, plotting with various sampling frequencies

Hi Rick,Thank you for your post.Allow me to elaborate. So I was given the continuous time function below:So this (I think) is the same as Xa(t) = e^(-j*2*pi*F0*t)...

## Re: DTFT, plotting with various sampling frequencies

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...

## DTFT, plotting with various sampling frequencies

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...

## Re: Simplifications With Eulers Equation (DTFT, DTFS)

Thanks Rick, I appreciate your feedback. That does make a lot of sense.

## Re: Simplifications With Eulers Equation (DTFT, DTFS)

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,...

## Re: Simplifications With Eulers Equation (DTFT, DTFS)

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...

## Re: Simplifications With Eulers Equation (DTFT, DTFS)

Thank you. I will read those articles. Thanks again. I greatly apprecate it.

## Re: Simplifications With Eulers Equation (DTFT, DTFS)

Thank you for the clarification. I will most certainly read your blog.:)

## Re: Simplifications With Eulers Equation (DTFT, DTFS)

Thank you. Wow that makes so much more sense now. Thank you so much for answering  that question :)While I have you, can you help shed some light on the below as...

## Re: Simplifications With Eulers Equation (DTFT, DTFS)

Hi,Thank you so much for your reply. Unfortunately, your graphic did not come through. Can you please try to re-post it?Thanks again :)

## Simplifications With Eulers Equation (DTFT, DTFS)

Hello,I am new to DSP and am taking a DSP class in university right now. One item that I am having trouble understanding (and my textbook doesn't seem to be addressing)...
