How phase relationship ?

Aarti said: 1 decade ago

We didn't get it. Please explain.

Xyz said: 9 years ago

I think it is voltage.

Rajashekar balya said: 8 years ago

Voltage is correct.

Ankit said: 7 years ago

Yes, voltage is correct. I too agree.

Anomies said: 7 years ago

Yes, it is voltage because in common mode voltage gain is zero which is not in differential mode.

Enyew said: 4 years ago

Phase relationship, because in differential mode the relation is out of phase but, in common mode, its relation is in phase.
