harminv

harminv(timeseries, timestep, start_freq, stop_freq)

Full definition:

[f,decay,Q,amp,phase,err]=harminv( timeseries, timestep, start_freq, stop_freq )

reconstruct time signal with:

real(amp(n) * exp(-1i*(2*pi*freq(n)*t-phase(n))-decay(n)*t)));

example:

t = linspace(0,(1/0.3e9)*5,1000);
u =     0.8 * sin(2*pi*0.7e9 * t + 0/180*pi);
u = u + 0.3 * sin(2*pi*0.3e9 * t + 0/180*pi);
[freq,decay,Q,amp,phase,err]=harminv( u, t(2)-t(1), 0, 1e9 );
