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...

Achievable phase resolultion depends on AD resolution and linearity and also harmonic distortion of the input signal. Assuming an ideal sine input, I expect about 0.1° resolution with 10 a Bit ADC.
