这篇论文将介绍对调频/调频遥测系统(频分多路复用)计算予加重计划和所需接收机中频带宽的方法。就目前使用的方法而言,系统工程师们是这样计算他们的系统予加重的:对比例带宽系统,按照3/2次方定律计算,对等带宽系统,则按照每倍频程6db锥度来计算,而择比例带宽通道和等带宽通道都使用的系统,通常是靠经验的办法。总频偏和接收机带对则采用先前表明成功的经验值。迄今为止,还没有研究出任何精确的方法能用于选宽系统的总频偏和接收机带宽。
This paper will introduce how to calculate the FM / FM telemetry system (frequency division multiplexing) for the emphasis plan and the required receiver IF bandwidth. For the currently used method, system engineers calculate their system to be aggravated: For a proportional bandwidth system, calculated according to the 3/2 th law of law, a peer-to-peer bandwidth system is calculated as a 6 dB taper per octave , While systems that use both proportional and equal-bandwidth channels are usually based on empirical methods. The overall frequency offset and receiver band pair are based on prior empirical success values. To date, no precise method has been developed for selecting the total frequency offset of the system and the receiver bandwidth.
