If you already know the frequency of the sinewave you want (I understood yes), you could try a lowpass filter, seem it seems your noise is at higher frequency components than your fundamental armonic. After lowpass filtering, you can try a FFT plot to check your fundamental armonic is the...
Hi,
For tracking I would suggest you to take a look to OpenCV libraries, there are some algorithms developed. Specially, I would take a look to the Lukas-Kanade method, which is implemented in matlab here. You also can find here a good tutorial.
So, as starting point begin to play and see...
It´s long time since I didnt use PICs. However I implemented a simple RS232 serial transmission between a 16F628A and another board to be controlled by ASCII characters. The only thing I want to add is that I got a lot of helpful information from both the application notes in the microchip...
Hi,
I would like to know if you can advice me about a good tutorial dealing with complex filters. I could not find too much googling.
Thanks in advance,

I will answer myself saying that I found this interesting.
However, more references are also welcomed!

Hi,
I have a question that seems simple but is surrounding my mind. From my understanding, a signal can be represented by its in-phase and quadrature componentes (which are low pass signals). The relationship is the following
A(t)*cos(wt +phi(t) ) = si(t) * cos(wt) - sq(t) * sin(wt) , being...
Re: Hello Wideband/UWB Gurus, how to measure "energy samples" from Energy Detector?
Hi x201s,
What I sent you is related for localization purposes with UWB, which is my topic of research for now. However, I think questions related with it may also be applied to your topic. I do not know much...
The short answer is yes. You can connect two pc's by using two usb-bluetooth adapters and you dont need to build/modify any circuit. For this type of devices you can search "bluetooth dongles" in google. I guess you would have to set up something like an "ad hoc" connection, i.e, point-to-point...
Re: Hello Wideband/UWB Gurus, how to measure "energy samples" from Energy Detector?
Hi X201s,
As far as I have read, the energy detection of a signal in a receiver is achieved by passing the signal through a square-law device, followed by an integrator and a sampler.
Also, it seems that to...
Radio frequency ranging (measuring distance) - radar perimeter distinction
Hi community,
I would like to know what is your opinion within the following problem:
I am trying to understand and develop a radio frequency ranging system, i.e., to measure the distance between a transmitter (which...
