Answer:A
If HD(ω) is the frequency response of the low pass filter, then for what value of ω, HD(ω)=1?
A. |ω| = π/D B. |ω| ≥ π/D C. |ω| ≤ π/D D. None of the mentioned
Explanation: The input sequence x(n) is passed through a low pass filter, characterized by the impulse response h(n) and a frequency response HD(ω), which ideally satisfies the condition,
