求翻译:As the time origin of waveform is shifted, the various sine and cosine coefficients of its Fourier series will change, but the sum of the squares of any two coefficients A and B will remain constant, which means that the average power of the waveform, a concept familiar to electrical engineers, is unaltered.是什么意思? 待解决

As the time origin of waveform is shifted, the various sine and cosine coefficients of its Fourier series will change, but the sum of the squares of any two coefficients A and B will remain constant, which means that the average power of the waveform, a concept familiar to electrical engineers, is unaltered.

原籍国的时间是转移的波形,各种必要条件和余弦系数的其傅立叶变换系列将改变,但该笔款项的方格的任何两个系数a和b将保持不变,这意味着平均功率的波形、熟悉的概念,电子工程师,是不变。

因为信号波形的时间起源被转移,它的傅立叶系列各种各样的正弦和余弦系数将改变,但任何二个系数A和B正方形的总和将依然是恒定,因此它意味着信号波形,一个概念知交的平均功率对电机工程师,是未改变的。

移动的时间起源的波形,及其傅里叶级数的各种正弦和余弦函数系数将会改变,但任何 A 和 B 的两个系数的平方和将保持不变,这意味着平均功率的波形,电气工程师,熟悉的概念是不变的。
