BASIC CONCEPT OF BROADBAND SEISMIC RECORDING

Mu Qiduo was a research professor at the Institute of Geophysics, SSB, the director of Research Division of Technological Management of CDSN. He had been engaged in the work ofbroadband seismology over a long period of time and had made significant contribution to the development of broadband seismology in China. He unfortunately passed away of lung cancer in Beijing on September 22, 1995, at the age of only 54. In order to commemorate Mr. Mu Qiduo, thisMonthly publishes here part of the contents of the teaching material on broadband seismologycompiled by him during his lifetime. This paper includes three parts: seismic observational systemas a linear system; compressing of broadband seismic recordings ; and form of broadband seismicrecordings.
