ABSTRACT:
To present a digital broadcast demodulator, in a demodulator of digital terrestrial wave broadcast for transmitting coded digital video and audio information in a packet form, capable of detecting packet synchronism stably and precisely, controlling the AGC, and processing the clock regeneration, in spite of inferior environments for receiving broadcast, such as deterioration of C/N of signal due to weak electric field, or strong ghost or multipath characteristic of terrestrial waves.
