在第一讲《绪论》中,我们谈到了遥测有别于一般通信的主要特点之一是同时在一个信道中传送几十路以至几百路信号。实现多路信号在一个公共信道中传输的方法就是我们这一讲要讲的遥测的信号划分问题。信号划分也叫信号分割或信道复用、信道多路复用等。这些名词都是一个意思,在本讲及以后各讲中,在不同的地方可能用不同的名词,这纯系习惯和
In the first introduction, “Introduction,” we talked about one of the main features of telemetry that differs from normal communications in that it can transmit tens or even hundreds of signals simultaneously in a single channel. The way to realize multi-channel signal transmission in a common channel is the signal classification problem of telemetry that we talk about. Signal division is also called signal division or channel multiplexing, channel multiplexing and the like. These terms are all meanings. Different pronouns may be used in different places in this and every subsequent talk, which is purely used to
