Abstract :
In this paper, we propose a new approach for VSB modulation. A pair of complex digital filters are used to accomplish waveform shaping and VSB modulation simultaneously. By the use of longer tap length, the high stop band attenuation eliminates the need for SAW filters at the output stage. To verify our approach, we use the Zenith VSB HDTV system as a test vehicle. A pair of 79-tap raised cosine digital filters are derived, implemented, and tested
