Let the input signal \(x(t)=\cos\left(2\pi f_o\,t+\varphi\right)\)be sampled at a rate \(f_s = \frac{1}{T_s}\) Hz.
The output signal \(y(t)\) is reconstructed from the sampled signal \(x[n]=\cos\left(2\pi\left(f_o/f_s\right)\,n+\varphi\right).\)
Input Frequency: \( f_o =\) (Hz)
Sampling Frequency: \(f_s =\) (Hz)
Phase: \(\varphi =\) (radians)
