Adakah kesaksian yang lebih besar dari ini

Tuesday, May 1, 2012



  • Signal overshooting prevention (overshooting max. 10 %)
  • Low noise and distortion
  • No adjust (only pilot tone level and output level)
  • High channel separation and spectral purity in common operation
  • RDS input and pilot sync. output makes easy to connect any RDS encoder
  • Microcomputer controlled
  • All parts are easy to buy (incl. crystal)
