    • Bandwidth Extension of Telephony Speech 

      Johansen, Martin Etnestad (Master thesis, 2009)
      The public switched telephone network (PSTN) restricts the acoustic bandwidth of telephonyspeech to less than 4 kHz. For compatibility with analog telephone networks, a 0.3 − 3.4 kHz passband is common. This bandwidth ...
    • S-bånd : telemetrimottaker 

      Johansen, Martin Etnestad; Würgler, Eivind Andreas (Bachelor thesis, 2006)
      Målet var å konstruere en mottaker for telemetridata. Den skal virke i Sbåndet, 2.2-2.3 GHz, med kanalavstand 500kHz. Mottatt signal er modulert etter Sundes FSK. Målet for mottakeren er å kunne motta data i hastigheter ...
