Fs = 100; % 信号采样频率
t = [0:1/Fs:5]'; % 信号采样时间
% Combine three signals into a three-column matrix.
% Each signal occupies one column.
x = [sin(2*pi*t), .5*cos(5*pi*t), sawtooth(4*t)];
y = amodce(x,Fs,'fm');    %调制.
z = ademodce(y,Fs,'fm');  %解调
subplot(2,2,1);plot(x);   %绘制源信号
subplot(2,2,2); plot(z);  %绘制调制解调后的信号
