如何用MATLAB计算波浪频率谱热心网友:看一个例子: Fs = 1000; % Sampling frequency T = 1/Fs; % Sample time L = 10

热心网友:看一个例子: Fs = 1000; % Sampling frequency T = 1/Fs; % Sample time L = 1000; % Length of signal t = (0:L-1)*T; % Time vector % Sum of a 50 Hz sinusoid and a 120 Hz sinusoid x = 0.7*sin(2*pi*50*t) + sin(2*pi*120*t); y = x + 2*...
