Hello, I have worked on a PFB (Polyphase Filter Bank) channelizer ~6 months ago. I read the XAPP1161 and used the accompanying matlab code, but not the FPGA implementation,...

Hello all, -
Your comments helped me a lot in preparing the presentation, and I
succeed in the interview! Now I have yet a final interview in which I
have to...

Hello Ced, thanks a lot. I am still working in my presentation. Thanks for the links. And I will definitely use your proclamation as I fully agree with it. Best...

Hello, your drawing is incredibly simple and extremely beautiful. I am using a similar one to illustrate Euler's Formula, but now I have added the point -1, to...

Yes I did thumb up, and answered, every comment because it is valauble to me and useful for my task. Each person contributed with his view on the topic.

Hello all. Thanks a lot for your valuable comments and good wishes. They will help me a lot in preparing my talk. Have a nice day,Sara

Hello Alan, thanks for your input. I will add it to my presentation, either at the introduction, the conclusion or both. Best regards. Sara

Hello, thanks a lot. I will add it to my talk, when I give an example of electrical circuit, to show that with complex numbers we can simplify the calculation (algebraic...

And thanks also for this part. I will also use it in my talk, When I give the example of an eléectric circuit to show that is easy to do the calculation with complex...

Good point. I will for sure speak of Euler and his identity (Swiss mathematician, being in Switzerland is a must :-) In the first 2 min when I introduce complex...

Hello Shahram. Very nice explanation. Will use part of it in the first 2 min. Thanks an regards,Sara

Hello Richard, thanks a lot for these valuable words. I sure will integrate them into my talk (sketch above). I also wanted to mention (maybe when I speak about...

I thought about, especially that in my last project was the software-defined-radio where I/Q data is very useful. But finally I decided to do something simpler...

Hello Mike and all, thanks very much for your answers. Here is a (ongoing) sketch of what I want to say. Please tell me if it sound reasonable and if you would...

Hello all, I hope you are doing well. I am in Switzerland (French part, Neuchâtel). Me and my family and friends are all doing well so far. They have closed all...

Hello I hope you are all doing well, in these difficult times. I would like to ask for your help as I have to prepare (for a job interview):a 10 min excerpt from...

The bi-linear transform maps (compress, warps) the whole frequency range of your s-domain function, 0 to inf, to the available frequency range in the z-domain, 0...

The link posted by JOS give a good comparison. I would mainly choose FIR if I want a linear phase, but seems not to be your case, as you want the same phase as...

Hello, there are different ways to transform an analog filter (s domain equation) to a digital filter. They correspond to different ways to map the s-plane into...
