SOME PROBLEMS RELATED TO THE USE OF DELAY LINES IN SEISMIC EQUIPMENT (O NEKOTROYKH VOPROSAKH, SVYAZANNYKH S ISPOLZOVANIEM LIHII ZADERZHKI V SEISMICHESKOI APPARATURE),

Abstract

Various design problems are discussed in using artificial delay lines with lumped parameters for delaying electrical signals in seismic equipment. Lines made up of T-filters and pi-filters are considered. Formulas are given for the transfer constant and for the upper and lower limiting frequencies of the passband for the line in terms of the parameters of the individual elements (resistors, capacitors and inductances) used in the line. A theoretical equation is derived for the frequency response of delay lines and calculations based on this formula show satisfactory agreement with experimental data. A circuit is examined for summation of electrical signals on a delay line as used in equipment for isolation and analysis of interference waves. (Author)
