21.
A signal x(n) = sin(ω0n + φ) is the input to a linear time invariant system having a frequency response H(ejω) If the O/P of the system is Ax(n -n0), then the general form of H(ejω) will be
Answer: Option
Explanation:
y(n) = A x(n - n0)
⇒ A sin (ω0(n - n0) + Φ)
⇒ A sin (ω0 n - n0ω0 + Φ) and ∠4 (ejω) is - n0ω0 + 2pk.
