The Common-mode signal--Adds the same amplitude opposite polarity signals on the differential amplification tube T1 and T2's base electrode. As the figure shows: The function of the common-mode signal: it has the synclastic effects to the two tubes, it will cause the commensuration increase of the current and the commensuration reducing of the collector potential, so the two tube's collector electrode output common-mode voltage Uoc is zero.
