ABSTRACT:
By shifting an RF signal to IQ components of a modulated baseband signal directly, the zero-IF technology and IQ interface are applied in ATSC, NTSC, and PAL systems, and VSB and SSB modulations. The mathematic calculations are based on Fourier transform for shifting the RF signal and for recovering a baseband signal from the modulated baseband signal.
