Phase Relationships (4)

 

 

Moving Ø Relationship:

- A combination of complete & partial Ø relationship

- This occurs with ‘dissimilar frequency combinations’

- What happen is ==> The Ø relationship changes with each cycle

 

▲ Moving phase relationship (Δλ=2Hz)

*In Next cycle ==> Twice offset (2 x 2Hz = 4Hz)

*e.g. Cancellation occurs at 180°, so if the offset is 45° then the cancellation happens after 4 cycle times
