    • In the present invention, a seismic receiver (100) contains an onboard digitizer (104) that samples and converts a signal from detected seismic energy into the digital domain. The receiver (100) contains an analog to digital converter (104), a transmission circuitry, and a link to the seismic detection circuitry (106). The signal from the seismic detection circuitry is converted into a digital signal, which is then relayed to the data recorder. These components are all resident to the receiver itself. Additional control circuitry (110) is employed to provide clocking and testing functions. These receivers communicate with one another, and provide sampled seismic data on an individual basis. The components may be prepared on a printed circuit board (PCB) and put inside the receiver cap. The PCB may be flexible in nature, as to provide a maximum of surface mounted components in the smallest amount of space.
    • 在本发明中,地震接收器(100)包含一个板载数字转换器(104),它将从检测到的地震能量的信号采样并转换成数字域。 接收器(100)包含模数转换器(104),传输电路以及到地震检测电路(106)的链接。 来自地震检测电路的信号被转换成数字信号,然后中继到数据记录器。 这些组件都驻留在接收机本身。 附加控制电路(110)用于提供时钟和测试功能。 这些接收器彼此通信,并且在各个基础上提供采样的地震数据。 组件可以在印刷电路板(PCB)上准备并放置在接收器盖内。 PCB本质上可能是柔性的,以便以最小的空间提供最大的表面安装部件。
