Hi everybody,
I have a sum of three sine waves with different frequencies. How can I get the same sines sum shifted of 90degrees?
Thank you

Hi,
You could implementing something along the lines of:
x = sin(linspace(0, 10*pi, 10000));
x_shift = zeros(1, numel(x));
x_shift(1:9000) = x(1001:10000);
plot(x)
hold on
plot(x_shift)
