双边频谱复系数简析

The Analysis of the Complex Coefficient of Bilateral Spectrum

详细推导了周期信号双边频谱的两种复系数表达式,并与《信号与系统》教材中的复系数表达式进行比较,发现该教材公式推导中有概念性错误,并更正之.

We have carefully analyzed both bilateral spectrum expressions of periodic complex coefficient of bilateral spectrum and compared it with the complex coefficient of bilateral spectrum in the textbook, ＂Signal and System＂. We have found that there are some conceptual mistakes in the textbook and corrected them.
