Abstract
PURPOSE: To simply determine a logarithmic decrement in a short time, by performing calculation and processing on a damped vibration signal through a differentiation circuit, a multiplication circuit, an absolute value calculation circuit, a logarithmic calclation circuit, etc.
CONSTITUTION: An input wave form is differentiated by the first differentiation circuit 1. The differentiated value is multiplied by a constant in a multiplication circuit 2. The output of the circuit 2 and an input signal are applied to an absolute value calculation circuit 3. The output of the circuit 3 is removed of its ripple by a low-pass filter 3a and then entered into a logarithmic calculation circuit 4. The output of the circuit 4 is differentiated by the second differentiation circuit 5 so that the differentiated value is indicated on a recording display unit. This results in determining the relation between requried amplitude and logarithmic decrement.
