本文介绍了一种新的巴克豪森信号测量系统，该系统最近开发用于软磁材料。该系统的主要特点是它使用能够完全控制磁通密度波形的自动数字反馈技术。该系统不仅能够控制正弦波条件下的磁通密度波形，而且能够控制三角形、梯形甚至任意条件下的磁通密度波形，磁通密度高达1.7T。测量的磁化频率为 25–75Hz，巴克豪森效应信号在 3.5–100kHz 的频率范围内检测到。
This paper describes a new Barkhausen signal measurement system that has recently been developed for use with soft magnetic materials. The key feature of this system is that it uses an automated digital feedback technique capable of fully controlling flux density waveforms. The system is capable of controlling the flux density waveforms not only under sinusoidal conditions, but also under triangular, trapezoidal, and even arbitrary conditions at flux densities of up to 1.7T. Measurements have been made at magnetizing frequencies 25–75Hz, and Barkhausen effect signals were detected over the frequency range 3.5–100kHz.
