摘要
设计了一款三通道地震波信号发生器,该发生器的整个系统由波形输出与频率脉冲计数两部分组成,其中波形输出可分别产生常规波形、存储波形和地震波形信号。应用和测试结果表明,该地震波信号发生器能基本满足应用需求。
The seismic wave signal generator is designed, which is made up of two parts ： a waveform output u- nit and a frequency pulse counter unit. The waveform output unit can generate conventional waveform signals, stor- age waveform signals and seismic waveform signals, respectively. According to application and testing results, the seismic wave signal generator can basically satisfy the application requirements.
