Abstract

This paper develops a multirate digital filter design for the vestigial sideband (VSB) modulator required in the analog TV transmission systems, like PAL. The design is based on a complex baseband VSB filter running at 13.5 MHz sampling rate, digital multirate techniques for increasing the sampling rate by the factor of 9, and a combination of multirate techniques and digital mixing to translate the signal to the 38.9 MHz IF picture carrier frequency.
