A signal $x(n) = sin(\omega_on + \phi)$ is the input to a linear time invariant system having a frequency response $H(e^{j\omega})$. If the output of the system is $Axn - n_0$, then the most general form of $\angle H (e^{j\omega})$ will be

  1. $-n_0 \omega_0 + \beta$ for any arbitrary real $\beta$
  2. $-n_0 \omega_0 + 2\pi k$ for any arbitrary integer $k$
  3. $n_0 \omega_0 + 2\pi k$ for any arbitrary integer $k$
  4. $-n_0 \omega_0 + \phi$
