If H(s) is the transfer function of a analog low pass normalized filter and Ωu is the desired pass band edge frequency of new low pass filter, then which of the following transformation has to be performed?
A. s→ s / Ωu
B. s→ s .Ωu
C. s→ Ωu/s
D. None of the mentioned
Answer:A
If H(s) is the transfer function of a analog low pass normalized filter and Ωu is the desired pass band edge frequency of new low pass filter, then which of the following transformation has to be performed?
A. s→ s / Ωu B. s→ s .Ωu C. s→ Ωu/s D. None of the mentioned
Explanation: If Ωu is the desired pass band edge frequency of new low pass filter, then the transfer function of this new low pass filter is obtained by using the transformation s→ s / Ωu.
