小的有将real function signal转成complex exponential function signal需求
使用hilbert transform产出analytic signal
t=0:0.1:10;
x=cos(2*pi*0.1*t);
y=hilbert(x);
plot(t,real(y),t,imag(y));
legend('real','imaginary')
When t=2.4，real part value=1.005,imaginary part value=0.06279
想问实部的cos^2+虚部的sin^2怎么会不等于1(不满足三角恒等式)?
