【经验】音频失真测量方法及Silicon Labs D类音频放大器音质交互式演示Demo
音频放大信号从频谱上分析,除了基波及各次谐波外,还有噪声的影响。音频设备噪声是随机噪声,通常用宽带白噪声表示。音频设备始终存在噪声,采用各种方法只能减小噪声而无法根本消除噪声。如图所示为包含宽带白噪声的音频放大信号频谱示意图。
判断音频设备音质的失真可以测量很多技术指标,目前最常用的失真测量方法是总谐波失真加噪声(THD+N)技术。THD+N是英文Total Hormonic Distorion + Noise的缩写,即“总谐波失真加噪声”。它是音频设备的一个重要性能指标。
由于在音频设备中,除了电子元器件的非线性导致的谐波失真,还有器件的噪声造成的影响。如果某台音频设备的总谐波失真满足国家/行业标准,但噪声较大,信噪比不达标,其技术指标仍然不能达到要求,因此仅用总谐波失真是不够的,还应考虑噪声的影响因素。THD+N比其他的失真测量更能说明音频设备的指标,用测量数据证明音频设备性能是最有说服力的。
THD+N用相对于信号电平的方法表示的,国内标准用百分比表示,即THD+N占基波能量的百分比。THD + N通常使用特殊的音频分析仪测量,这是一种特殊的频谱分析仪,带有可切换滤波器。测量时在放大器处输入正弦信号,并查看其与放大器输出端的总功率谱相关的输出功率。由于放大器的音质很大程度上取决于所选的放大器(输出功率)和频率放大,因此必须在不同功率和不同频率下进行测试。
如图所示为THD+N音频分析仪测试原理图,音频信号经过增益选择、跟踪陷波滤波、带陷滤波、RMS检测器等处理后得出。在工作时,陷波器跟踪正弦波的基波频率上,基波被很大衰减,而谐波、宽带噪声和任何其他处在陷波器频率上下的干扰信号则可以无衰减地通过。

SILICON LABS公司的Si8241/44芯片在单芯片上集成了几乎所有D类音频放大器的先进特性,从性能、体积、成本各方面来说,都是音频设计者的理想选择。Si8241/44芯片拥有高达8MHz的调制工作频率,能实现最佳THD。该芯片还具有>100 V/ns的高门槛噪声免疫能力,而且输入和输出完全隔离,将噪声影响降到最低。此外,芯片内部集成了一个可编程死区时间控制门,可以进行精确的可编程死区控制,使其达到尽可能低的总谐波失真和最佳效率的平衡。
为了让用户了解该芯片的优异的总谐波失真和噪声特性,Silicon Labs公司提供一个D类音频驱动程序交互式演示工具,可以在可听频谱上查看Si824x D类音频驱动器的音质表现。该演示显示了总谐波失真+噪声(THD + N)比,这是声音音频放大器的通用测量。120W是完全(100%)功率。
笔者试验了几个不同音频输出功率下的总谐波失真+噪声(THD + N)比模拟测试结果,聆听着悦耳的音乐,感受下Si8241/44超级D类音频放大芯片带给我们的震撼!
