Method and apparatus for measuring the frequency of a received signal |
摘要 |
A method of measuring the frequency of a received signal comprising the steps of: generating a first phase signal by digitising the phase of the received signal; delaying the first phase signal by a predetermined amount to generate a second phase signal; calculating a phase difference between the first and the second phase signals; and calculating the frequency of the input signal from the phase difference.
