Hi Ted,
 
  I have designed a digital period extending filter. It is now  incorporated 
into AmaSeis. For filtering WinQuake files, you can use my  "WQFilter.exe" 
program. To obtain the program, download "seismic_dataq.zip" from 
 
_http://www.jclahr.com/science/psn/mcclure/wdq_utilities/index.html_ 
(http://www.jclahr.com/science/psn/mcclure/wdq_utilities/index.html) 
 
 Extract the files "WQFilter.exe" and "WQFilterHlp.txt" from the  zip.
 
  I can send you a description of the filter, if you ask.
 
Regards,
 
Bob
 
>Hi Everyone,  The Horz. Pendulum Sensor, I finished weeks ago, is  working 
fine but will be relocated, as part of a new display at the Museum of  Mining 
and Geology, in the spring.  They are closed during the Winter  months.  So I 
will need to replace everything, if I am to continue these  endeavors.   I am 
thinking I would like to build a vertical  sensor.  I have read that the AS1 
has a period of 1.5 seconds, but is  extended electronically.
 
 Is there a program which does this? Maybe an article which explains  it?<
