1.	What is the equivalent lowpass representation obtained by performing a frequency translation of X+(F) to Xl(F)= ?(a) X+(F+Fc)(b) X+(F-Fc)(c) X+(F*Fc)(d) X+(Fc-F)The question was asked in an online interview.I would like to ask this question from The Representation of Bandpass Signals in portion Sampling and Reconstruction of Signals of Digital Signal Processing
Answer» The correct option is (a) X+(F+Fc) To elaborate: The ANALYTIC signal x+(t) is a BANDPASS signal. We OBTAIN an equivalent lowpass representation by performing a frequency translation of X+(F).
