phase difference 2 signals.

is possible whit fpga FFT or similar metod measure a phase difference from 2 PULSED-sinusoidals signals? the freq of signals is 60MHz but the duration of signals is 0.5uSEC, and the PRF of pu...

1) time domain option is unlikely to have good resolution since 60MHz running at sampling freq of say 240MHz means only 4 samples per cycle.

2) fft option may be better. You can model that in matlab: generate stimulus then apply fft and see phase.
