摘要：This white paper talks about the measurement of phase angle using Phase Locked Loop and printer port.. The phase detector compares the phase of a periodic input signal against the phase of the output of voltage controlled oscillator and generates an average output voltage Vout which is linearly proportional to the phase difference, ?ø between its two inputs. This output voltage is measured using the parallel Printer port of a PC.
