Any time domain signal is composed of some sinusoidal signals. Each sinusoidal signal with frequency Fin can be recovered by the sampling frequency at least twice of Fin. I know that for the sinusoidal signals, two sampling points can alreay confirm this sinusoidal signal, but how it can recoverd the amplitude??
For example, if the sample points are at A and B, the signal time domain information can be confirmed, but how do we know its sinusoidal amplitude? Thanks.
