基于功率谱密度的平面十字阵列被动声定位matlab仿真程序(Based on planar cross power spectral density array of passive acoustic localization matlab simulation program)

In any power system, stability is always a important parameter. To check the stability of a synchronous generator which is connected with the grid is the power angle and freq need to know. With the help of this simulation model one can easily find Power angle and Freq.

模拟单边带调幅及解调产生300 ~ 3400Hz的调制信号，画出时域波形及频谱；  产生载波信号，频率自定义，画出时域波形及频谱；  产生加性高斯白噪声，画出时域波形及频谱；  单边调幅，画出叠加噪声后的调制信号和已调信号的波形及频谱；  设计滤波器，画出幅频响应图；  解调，画出解调后的信号时域波形及频谱，并对比分析。(Simulation of single sideband amplitude modulation and demodulation )

说明：  利用模拟信号对能量法进行验证，主要求解振幅值，能量值，频率包络值(Analog signal on the energy method used to verify, mainly to solve the amplitude value, energy value, the value of the frequency envelope)
