经典谱估计-周期图法 实现正弦波加正态白噪声信号的谱估计-Classical spectrum estimation- the realization of periodogram normal sine wave plus white noise signal spectrum estimation

function [f,Py,w,fp,Pmax]=spectrum(ug,dt) spectrum Compute the one-sided psd from the power spectrum refer to the help of fft and periodgram.m. codied by Dr. Ping TAN June, 2005- function [f, Py, w, fp, Pmax] = spectrum (ug, dt) spectr
