代码说明:

说明:   基于matlab 的叠加高斯白噪声的正弦信号频谱分析,给定正弦函数x=sin(2πf0n/N+π/3)+sin(2πf1n/N+π/4),设定f0.f1的值,加了噪声之后做快速傅里叶变换,在matlab中分析其频谱,验证是否与f0,f1的值符合。再变换N值,看随着N值的变化对应点是否符合及有何变化。(Matlab based on the superposition of Gaussian white noise sinusoidal signal spectrum analysis, given the sine function x = sin (2蟺f0n/N+蟺/3)+sin (2蟺f1n/N+蟺/4) set value of f0.f1, do a quick noise Fourier transform to analyze the spectrum in matlab, verify that with f0, in line with the value of F1. Transform the value of N, see change as the value of N corresponding points of compliance and what changes.)
