| 释义 | dynamic gain 动态增益 The specific magnitude ratio of the steady state amplitude of the output signal from an element or system to the amplitude of the input signal to that element or system, for a sinusoidal signal,i.e.,it is expressed as a ratio, or in a decibels as 20 times the log of that ratio for a specified frequency. 对某一元器件或系统而言,其稳定状态下输出信号(正弦波)的振幅与输入信号的振幅之 比,常用这一比值或以分贝为单位来表示增益。分贝的大小为在既定工作频率下,上述比值 取常用对数,然后乘以20。 |
