2 small magnification difference between the balanced output circuit

  
A balanced output mentioned, people tend to immediately think of the positive phase amplifier output terminal increases 0P amplifier as the inverting amplifier circuit, normal
2 small magnification difference between the balanced output circuit - schematic

and reversed phase output set to lose balance fH o in the DC circuit, although this method can be used, but as Tiao are wide -band signal, the inverting amplifier cup drift is a problem. Since this circuit. OP measures also zoom in and drift d is equal to the soil, so even if the input frequency of change seven phase distortion does not occur 4
