| Summary: | 碩士 === 國立中央大學 === 電機工程研究所 === 83 === In this thesis, we introduce Zenith VSB CATV system and propose
a new apporach for VSB modulation. A pair of digital filters
are derived, analyzed, and implemented to verify the new
approach. I n the top-down design methodlogy, we have used
Matlab, SPW, Veri log, and Cadence to obtain initial design,
fine tune the design, and run system simulation and gate level
simulations. To verify the approach, we use Zenith VSB HDTV
system as a test vehicle. W e model the VSB modulation and
demodulation system in mathematic al equations. The shaping
filters beimg implemented successfully generates VSB signals
for the target system. Finally, we use CCL standard cells to
implement the shaping filters.
