Hi Guys,
One thing is confusing me. Let say I have a sine signal of frequency 'Fc' and I transmit it. It comes back bouncing from a moving object (Lets assume human's heart). I am assuming environment free of noise for the time. Then Would the coming signal be sin(2*pi*Fn*t + theta) where Fn = Fc + Fd ?
Where theta is phase delay and Fd is change in frequency.
Right?
Fd (Change in frequency) would be variable or constant?
Or If I consider noise what would be approximate receiving signal?
Any help would be appreciated.
Thanks!
