A. Impulse invariance B. Mapping of derivatives C. Bilinear transformation D. None of the mentioned
Explanation: In the case of bilinear transformation, where aliasing is not a problem, it does not matter whether the frequency transformation is performed in the analog domain or in frequency domain.
