五、联邦德国的台阵设施1.GRF 台阵的野外设施在单分向台站,拾震器输出分成4级,放大器增益依次为1、4、8、8,这样,经过4档放大器的信号较第一级输出放大倍率为256。这4级输出分别由16位的模数转换器数字化,并送入 LSI 2/20计算机。在计算机中选择这4个输入中尾数有效数字最多而又未限幅的一个,取12位(含符号位),与4位阶码组成新的16位数,经过1200波特的数传机经电 Fifth, the Federal Republic of Germany array facilities 1.GRF array of field facilities in a single station, the pickup output is divided into four, the amplifier gain followed by 1,4,8,8, so that after 4 files amplifier signal More than the first level of output magnification of 256. The four outputs are each digitized by a 16-bit analog-to-digital converter and sent to an LSI 2/20 computer. In the computer, select one of these 4 inputs whose mantissa has the largest but not limited number of significant digits, take 12 bits (including sign bits), compose a new 16-bit number with 4 bits, After electricity
