Set Up Low Pass Filter This happens because the relation between the seismic measurements and the magnitude is complex and different procedures will often For earthquakes that occurred between about 1890 (when modern seismographs came into use) and 1935 when Charles Richter developed the magnitude scale, people went back to the old records and compared the seismograms from those days with similar records for later earthquakes. 0000340647 00000 n Designed to be the hub of airport services, the airport can have two planes take off and two planes land at any time; it also has two helipads.

The time scale and date display is derived from the file header, where the start time in seconds from Midnight Jan 01, 1970 GMT is stored. It is only as accurate as the PC system clock was at the time the recording was initiated. In order that a 24 display always be available, the first line of the plot is the hour at which recording was initiated, not 00:00 GMT as seen in the LDEO plots. Elapsed time is only as accurate as the crystal on the Dataq A/D board. Our experience with several of the DI-194 and DI-154 devices is that the sample rate is about 300 parts per million fast on all of them, so that about 1.0 seconds per hour is gained. This error can be negated by modifying the header element that stores the sample period to make it shorter by 300 parts per million. If the PC system clock was in error, it can also be corrected by changing the time information in the header.

The Windaq acquisition program period averages this data stream down to the user selected sample rate. This technique helps to reject hum and high frequency noise, and provides greater resolution than the number of bits of A/D conversion. When more than one channel is activated, multiplexing is accomplished at the 240 samples per second rate, so there will be about 4 milliseconds time skew for each succeeding channel. We have written a Visual Basic program "WDQ_Edit.exe" for inspection and modification of the WDQ file header, as well as other useful functions, such as file splicing, merging single files into multiple channel files, rescaling file data, and downsampling files. `` detail '' is quite different from traditional square dancing is all about as it is quite different traditional.
