D. None of the mentioned
Answer:A
Which of the following is a low pass-to-high pass transformation?
A. s→ s / Ωu B. s→ Ωu / s C. s→ Ωu.s D. None of the mentioned
Explanation: The low pass-to-high pass transformation is simply achieved by replacing s by 1/s. If the desired high pass filter has the pass band edge frequency Ωu, then the transformation is
