What is the error in magnitude at the frequency ωk?
A. G.A(ωk) + Ad(ωk)
B. G.A(ωk) – Ad(ωk)
C. G.A(ωk) – A(ωk)
D. None of the mentioned
Answer:A
What is the error in magnitude at the frequency ωk?
A. G.A(ωk) + Ad(ωk) B. G.A(ωk) – Ad(ωk) C. G.A(ωk) – A(ωk) D. None of the mentioned
Explanation: The error in magnitude at the frequency ωk is G.A(ωk) – Ad(ωk) for 0 ≤ |ω| ≤ π, where Ad(ωk) is the desired magnitude response at ωk.
