It is stated that two ways to describe random analog noise are the uses of the standard deviation on collection of converter digital-output samples and a constant crest factor to describe a noise converter with a peak-to-peak value. It discusses the description of the noise specification that ...
简单回顾一下,peak就是以信号电压绝对值为阈值参照,RMS就是将信号转换信号的RMS值为阈值阈值参考。 我们常说的220v交流电,并不是指电压的peak to peak峰值差是220v,而是其等效直流电是220v。 AC与RMS转换 与RMS值的直流电可以产生相同的功率 RMS=230v的交流电与230v的直流电做工相等,所以只要把交流转换成直流,就...
也就是说,rms和peak是通过下列公式相互转换的:rms=peak/根号2,peak=rms*根号2。其中,rms是描述信号强度大小的指标,而peak则表示信号波形峰值的大小,两者在不规则波形分析过程中均具有重要意义。 RMS习惯称为均方根值,是英文Root Meam Square的首字母缩写。 Peak(英文峰)是波形的峰值。 峰值是指一个周期内信号最...

The article focuses on the use of the root mean square (rms) and peak-to-peak values in describing random analog noise. Random analog noise is described in various ways, including the use of standard deviation of a several converter digital-output samples, which is equal to the rms. Another...
把RMS(root mean square)和Peak意思明白了,自然就明白区别在哪儿了。
peak是峰值电流,rms是均值电流,一般驱动器如EZM552,peak=1.4*rms,也有个别是按1.2倍关系来设计。
峰峰值(Peak-to-Peak Value)表示信号的峰值与谷值之间的差值,它反映了信号的振幅范围。 总结起来,PV和RMS值是描述信号强度和功率的常用参数。PV值表示信号的峰值,RMS值表示信号的均方根值。它们的计算方式不同,物理意义也不同。在实际应用中,PV值常用于测量信号的峰值,而RMS值常用于测量信号的功率或能量。除了...
