图1所示电路是一种通信测试的测试信号小型发生器电路。其功能是以事先确定的模式仿真数据流,并用此类模式检查电缆的功能或接收机的功能。本电路根据信号交替反转码(AMI码)产生测试信号。在这种编码方式
The circuit shown in Figure 1 is a small test generator for communication testing. Its function is to simulate the data flow in a predetermined mode and to check the function of the cable or the receiver with such a mode. The circuit generates a test signal based on the alternating signal (AMI code). In this encoding
