Hi Martin
Thanks for the reply. Right now I am preparing draft for proposal. As soon
as I finish my draft I will upload it so that mentors can evaluate it.

Mitul,

look at the emails we sent out to the other GSoC applicants (go to the 
mailing list archive if necessary). You'll need to start working on a 
proposal. Also, for this project, you'll need to make sure we know you 
know what you're doing from a signal processing perspective.

Regarding Project, I've found one good document
from
agilent.

Summary of what I understood from that document:
1) Using usrp b210 I can generate pure tone sine wave as test signal
2) I will connect DUT ( device under test ) with external components to
the usrp  and measure transmitted and reflected signal
3) The amplitude and phase of the received signal will lead to different
parameters

How can we measure phase between two sine waves using FPGA? The method
of zero crossing is advised or not?
Please give you inputs on this project.

Taking the average of all datas may works :)
Airprobe uses this method to calculate the phase difference.

Hi,
Thanks for reply.
I want to measure phase between reference signal and signal coming from
DUT(Device Under Test). It may possible that due to non-linear
characteristic of the device, there are changes in frequency and amplitude
of signal. In this case the method you mentioned will give correct phase?

Thanks

Hi,

> How can we measure phase between two sine waves using FPGA?

Supposing the two sine waves have the same frequency.
For two discrete complex signals, v1 and v2. we can compute the phase
difference as follow.

v3 = v1 * conj(v2)
phase diff = arctan(imag(v3) , real(v3))

(conj() means conjugate)

Zhenhua
