Multi-Path Generator(DMPG-100)

• Multipath generation for DTV
  
• Option to StraTek 8-VSB modulator VT-100

• Direct digital interface to StraTek 8-VSB modulator VT-100 which conforms to the US ATSC HDTV standard
  
• Multipath parameter sets easily entered using keypad and displayed on LCD with the last used multipath pattern retrievable on next power up
  
• Full digital implementation to preserve signal fidelity

• Generation of static ghosts with their attenuation, time delay, and phase parameters independently controllable by accepting 12 bit 8-VSB modulated input
  
• Six independent paths, including one main path and five ghost paths
  
• Relative attenuation variable from 0 to - 40 dB in steps of 1 dB
  
• Relative time delay variable from -10 to 50 ms to accommodate both pre- and postghosts in steps of 0.1usec.
  
• Relative phase variable from 0o to 360o in steps of 1o
  
• Final output incorporating multipath fading available as analog output using 12 bit DAC
