用于控制音质的NF型调制控制电路，因仅能进行低音和高音的增强和衰减，所以不能进行细微的频率特性的补偿。述有，如果想使可听频带域的任意频率均可变，一般使用被称为图形均衡器的装置。这里使用DSP的例子在不断增加，如果要使用简单的电路则使用OP放大器较好。这种图形均衡器是将补偿的中心频率分割为5～7份，分别进行控制，由5个RLC电路组成，十分实用。分割的各个频率是以可听频率范围为对称轴均等分配而决定。-NF-modulation control circuit to control the sound

对重分配小波尺度谱存在着时、频分辨率不能同时达到最佳及当振动信号中存在着能量较大的噪声时会降低其时频分布可读性的缺陷，提出一种基于参数优化和奇异值分解(SVD)提高重分配尺度谱时频分布可读性的方法。首先利用Shan—
non熵方法优化重分配尺度谱基函数的时间．带宽积(TBP)，克服其时、频分辨率不能同时达到最佳的缺陷，再对重分配尺度谱
进行SVD降噪降低噪声干扰影响，提高时频分布的可读性。最后用该方法对仿真信号和滚动轴承故障信号进行了分析，结果表明该方法的时频聚集性更好，抗噪能力更强，能
