So that means I get 0 volts when I touch one side of the 120V in my electrical service to the 120V other side? I was afraid I might see 240V. If those signals are equal in amplitude and 180 degrees out of phase, it means they are *differential*, you will see 240v, and you had better not short them together. OTOH, if they are common-mode signals, they are in-phase and you can short them together to your heart's content - no current will flow. Again, you seem to have the IEEE definitions of "differential" and "common-mode" exactly reversed in your head. -- 73, Cecil http://www.w5dxp.com |
