摘要：
In audio amplifiers, distortion can be generated by a signal-current circuit (the copper foil of a P/C board and the wiring of the circuit components), because of the influence of nearby magnetic materials (the chassis, casing, power source transformer, etc. ). This paper shows the phenomenon of generation of distortion in amplifiers caused by the B-H curve of magnetic materials and the dependency of such distortion on the current and frequency of the circuit. Techniques are presented for eliminating these distortions.
