1数传系统可靠性设计信息在电缆上传输过程中,可能会由于受干扰、丢码等原因,从而产生错误。因此数传系统可靠性设计就尤为重要。可靠性设计可分为硬件设计和软件设计,硬件方面是保证系统能够正常运行的前提条件,软件方面能够保证通信的可靠性和较低的误码率。1.1硬件的可靠性设计硬件方面主要采用抗干扰设计,例如,采用模拟高通滤波器去除工频干扰,对通信信号以外
1 digital system reliability design information in the cable transmission process may be due to interference, lost code and other reasons, resulting in errors. Therefore, the reliability of digital system design is particularly important. Reliability design can be divided into hardware design and software design, the hardware is to ensure that the system can be a prerequisite for the normal operation of the software to ensure the reliability of communications and lower bit error rate. 1.1 The reliability of hardware design Hardware mainly anti-jamming design, for example, the use of analog high-pass filter to remove the frequency interference, the communication signal
