A signal x(n)$$ = \sin ({\omega _0}\,n + \phi )$$ is the input to a linear time-invariant system having a frequency response $$H({e^{j\omega }})$$.If the output of the system is $$Ax(n - {n_0})$$, then the most general form of $$\angle H({e^{j\omega }})$$ will be
A
$$ - {n_0}{\omega _0} + \beta $$ for any arbitrary real $$\beta $$
B
$$ - {n_0}{\omega _0} + 2\pi k$$ for any arbitrary integer k
C
$${n_0}{\omega _0} + 2\pi k$$ for any arbitrary integer k
D
$$-{n_0}{\omega _0} + \phi $$
