Development of portable instrument for amplitude - frequency characteristic 便携式低频幅频特性测试仪的研制
Amplitude - frequency response characteristic 幅频特性
Malfunction of amplitude - frequency characteristic of ecg and its solution 心电图机幅频特性不合格原因及处理办法
Amplitude - frequency response 幅频响应
In the end , we discuss the relationship between the parameters in the cure of amplitude - frequency and the physical parameters of the system , and optimize the parameters 最后详细研究了系统的幅频响应曲线中的各参数与系统物理参数之间的关系,并进行了参数选择。
