随着伪随机信号技术在系统测试、环境模拟、数据传输、脉码通信等领域中日益广泛的应用,研制通用伪随机信源显得十分必要。我们研制的GPR—1型通用伪随机信号发生器,与国内现有伪随机信号发生器相比,有以下特点:1.通用性强。它不仅适用于自动控制系统的动态特性测试,环境模拟等一般用途,还适用于各种速率的数传机、PCM一次群,二次群的测试等特殊用途;2、集成度高。大部份采用了中规模集成电路;3.体积小、重量轻、使用携带方便。
With the increasingly wide application of pseudo-random signal technology in the field of system testing, environment simulation, data transmission and pulse code communication, it is necessary to develop general pseudo-random signal source. The GPR-1 general-purpose pseudo-random signal generator we developed has the following characteristics compared with the existing domestic pseudo-random signal generator: 1. High universality. It applies not only to the automatic control system dynamic characteristics testing, environmental simulation and other general purposes, but also for a variety of speed data transmission machine, PCM primary group, secondary group test and other special purposes; 2, high integration. Most of the use of the scale of integrated circuits; 3 small size, light weight, easy to carry.
