In this tutorial, we present a simple method to make a rudimentary transfer function measurement, using Frequency Domain Analysis. This method was discovered on a search for a more direct procedure, and so this tutorial should be modified if such a method is found. The strategy is to physically perturb one portion of the object with an oscillatory drive, and observe the maximum displacement of another portion as frequency is varied.

Transfer Function Measurements

In this tutorial, we present a simple method to make a rudimentary transfer function measurement, using Frequency Domain Analysis. This method was discovered on a search for a more direct procedure, and so this tutorial should be modified if such a method is found. The strategy is to physically perturb one portion of the object with an oscillatory drive, and observe the maximum displacement of another portion as frequency is varied.
