In the phase difference measurement system, a reference VOR signal and a variable VOR signal are received and multiplied by locally generated sine and cosine signals. The multiplication produces two sine and two cosine signals at very low frequencies which are equal to the difference between the ...

An exclusive OR gate is used to compare the reference and variation signals, after they are divided in frequency, to produce a composite signal which has a duration indicative of VOR bearing. The composite signal is then clocked, counted and averaged over a number of intervals and fed to a ...
摘要：PURPOSE:To detect accurately the point where each signal of VOR passes through a zero potential and detect a phase difference by generating a division output according to chop signals of the same frequency generated synchronously with the reference phase signal and variable phase signal of said...
