COURSE OBJECTIVES:
Description and analyses of response of dynamic systems. Comparison of transfer function with frequency response and application on seismograph. Comparison with dynamic magnification of mechanical seismograph. Generalization to the system of n degrees. Achieve seismograph calibration skills and competency for using the seismograph by measuring the electromagnetic and broadband seismograph characteristics. Distinguishing seismograph types, and introducing the measurement of time as an unavoidable factor in geophysical observations and measurements.

COURSE CONTENT
Seismograph as a measurement system. Characteristics of static and dynamic measurement systems (transfer function, frequency response function, poles and zeros). Mechanical seismograph (indicator equation, dynamic magnification, main parts, construction), electromechanical seismograph (dynamic characteristics, main parts, construction). Experimental measurement and frequency response estimation, broadband seismographs. Accelerographs. Time and GPS.

LEARNING OUTCOMES
After completing the course of Seismometry, the student should be able to:
- Describe and analyze the responses (characteristics) of dynamical measurement systems,
- Determine the transfer function and frequency characteristics of the RC circuit and
seismographs using Laplace and Fourier transforms, and generalize findings to the n-degree system,
- Analyze the dynamical system using the poles and zeros of a transfer function,
- Assemble electromagnetic seismograph from components, and calibrate it for a number of frequencies,
- Calculate and graphically display the measured frequency response, and analyze the working range of the instrument.
