urn:hdl:2117/87393 Sampling in-phase and quadrature components of band-pass signals Mariño Acebal, José Bernardo Masgrau Gómez, Enrique José Àrees temàtiques de la UPC::Enginyeria de la telecomunicació Sampling Sampling Band-pass signals Complex-envelope In-phase and quadrature components Mostreig A filtering method for sampling the lowpass equivalent of a bandpass analog signal is introduced. This input is sampled at exactly twice the sampling rate of the in-phase and quadrature components provided at the output. The sampling frequency determination and the lowpass decimator filter design are straightforward. The practical implementation of the sampling method is accomplished by the polyphase realization of the filter; this implementation is particularly suitable for linear phase FIR designs.
