Geophones
L-28LB
| Natural Frequency [Hz] | 4.5 |
| Weight [g] | 140 |
| Sensitivity [V/(m/s)] | 31.3 |
We define the parameters of the geophone and we plot its bode plot (figure fig:L28LB_bode_plot).
w0 = 4.5*2*pi; % [rad/s]
ksi = 0.38;
G0 = 31.3; % [V/(m/s)]
G = G0*(s/w0)^2/((s/w0)^2 + 2*ksi*(s/w0) + 1); <<plt-matlab>>
L-4C
| Natural Frequency [Hz] | 1 |
| Weight [g] | 2150 |
| Sensitivity [V/(m/s)] | 276.8 |
The transfer function from the velocity and the measured voltage is defined below.
Its bode plot is shown on figure fig:L4C_bode_plot.
w0 = 2*pi; % [rad/s]
ksi = 0.28;
G0 = 276.8; % [V/(m/s)]
G = G0*(s/w0)^2/((s/w0)^2 + 2*ksi*(s/w0) + 1); <<plt-matlab>>
