Is it possible to calculate the phase and signal amplitude from data gained from FFT?(adsbygoogle = window.adsbygoogle || []).push({});

For instance, if I have a samples from a signal B+A*cos(ψ), is it possible to obtain A and ψ?

Extra challenge: is it possible to do so without division? (I am looking to put this on a DSP and division is expensive)

Thanks!
