在ＭＡＴＬＡＢ中非平稳信号的调用函数，生成以Ｔ０为中心的双边指数调幅信号-MATLAB Central Africa in a smooth signal transfer function, T0 generation to the center of the bilateral index AM signal

模拟通信中的双边带常规调幅示例，仅供大家参考，学习之用！-Simulation bilateral communication with conventional AM sample, only for your reference, learning!

Matlab实现FFT变换代码（包括单边谱及双边谱）-Matlab realization of FFT transform code (including unilateral and bilateral spectrum spectrum)

用FFT计算信号的功率谱密度时，需要先计算FFT，再计算双边谱密度，然后计算单边谱密度。在matlab里注意FFt要除以采样点数，计算双边谱时要注意除以频率分辨率。 - When calculated using the FFT power spectrum density signal, you need to calculate the FFT, and then calculate the bilateral spectral density, and then calculate
