Help for common mode wave

[apriori]

Hi Sirs,

I have a question need for your help.

What is the common mode wave or common mode current?
Does it different with diffierential mode?

Thanks.

common mode signal have the same phase and amplitude(usually even harmonics)

differential signal which have 180 degree phase shift but have the same amplitude.(usually odd harmonics)

 

[kishorekumar_ms]

common mode wave is one in which all mode fields resonate at same frequency.... these generate linear polarization.

To define common-mode or differential for something, it must have two inputs. If the two inputs are different (it may be voltage or current), you will have a differential output. If the inputs are the same, you will get a common-mode output.
Hope it works, good luck
