Precision digital phase meter |
摘要 |
A method of measuring phase includes receiving an analog signal; converting the analog signal into a digital signal; representing the digital signal as N sets of samples; aligning the N sets of samples to a common time frame; removing zero bias drift from the digital signal; and calculating a phase of the analog signal based on the digital signal with the zero bias drift removed. The phase can have a time resolution substantially equal to a time between adjacent samples.
