对功率超过250千瓦的大功率发射机来说,费用因素如初投资和运行费变得越来越重要。为了降低这些费用,德律风根公司研制了一个广播发射机的新系列。本文专门叙述应用于这些广播发射机的德律风根脉宽调制阳极调制系统(简称“PANTEL”)。 For high-power transmitters that exceed 250 kilowatts, cost factors such as initial capital and operating expenses become more and more important. In order to reduce these costs, Telefunken has developed a new series of broadcast transmitters. This article describes the Telefunken Root Width Modulation Anode Modulation System (“PANTEL”) for these broadcast transmitters.
