Hello.
I read some article telling thaf transformer not only reject common mode noise ans also high frequency differential mode noise.
For common mode noise, the rejection is obvious as identical signals on both wires connecting two end termnals of one side of transformer generates zero magnetic field so no coupling to other side.
But differential mode is just what transformer is supposed to receive. How high frequency in this mode is rejected from transformer? Is due to high impedance for high frequency as transformer is nothing but inductor when looking at only one side?
