Phase (2)

 

 

180° Phase relationship:

- Out of phase

- Totally subtractive  

 

▲ 1) B begins at 180° of A

2) Throughout the cycle, they are moving 'opposite' direction

3) This makes 'Total Cancellation'

 *Latency also may make phase

 

0° relationship is the only relationship which can ‘double’ (total additive)

ex) [10 (Amp.) + 10] + 10 = 2 x 10 + 10 = 3 x 10

    

180° Relationship is the only relationship which can 'totally cancel' (total subtractive)

ex) (+)10 (Amp.) + (-)10 = 0

       (+)10 (Amp.) + (-)5 = +5

 

*Amp. = Amplitude
