也就是说不适合高精度测量(DC/低频) ,因为里面有 1/f 噪声,不适合本公式,应该使用积分模型!!! 是最常用的工程级噪声估算公式 从公式看只要知道带宽(Hz)和噪声密度(V/√Hz),就能快速评估噪声底线。 个人觉得如果公式对的话,计算热噪音和运放、ADC 输入噪声会很快:前者用 ,带入上式,后者是使用 datasheet 提...
01额定噪声功率(Rated Noise Power)其定义为:连续向扬声器输入模拟噪声信号(将粉红噪声经过带通滤波和限幅后的信号),在100小时内连续工作没有过热和机械损伤,这个功率就称为扬声器的额定噪声功率。该功率的大小与失真度无关,所以通常比前述的标称功率大1.5至3倍左右。目前国内外厂家生产的扬声器,铭牌上的标志常见的就...
I am using an E5052B Signal Source Analyzer to acquire phase noise data with a carrier at 20.460802MHz from 1Hz to 5MHz. I am trying to convert the Phase Noise data exported as a .csv file to RMS Jitter(radians), but I'm having trouble following the units through the process. To...
