There is a analog signal in the form as below:
$$ f(t)=A \sin(\omega(t) t+\phi)+B \sin(\omega(t-t_1) t+\phi_1) $$ Where $$B<<A$$
We are going to calculate $\phi, \phi_1, t_1 $,using dsp. But since $B<<A$ and due to quantization level limitation, we can not extract data precisely. Is there any suggetion how to deal with that?
Thank you for your kind replies
