School of Mechanical and Aerospace Engineering MAE 3113 Mechanical quantities have distinctive time-amplitude properties which can be classified as follows: Static – constant in time (DC signal) Dynamic – varying in time (AC signal) Simple periodic Complex periodic Step Ramp Pulse Non-deterministic – random or chaotic Types of Input Quantities Trivial Case These are the type of signals we are interested in since they occur most often in a measurement

School of Mechanical and Aerospace Engineering MAE 3113 There are basically two ways to analyze a dynamic signal Fourier Analysis Fourier Analysis is based on the concept that real world signals can be approximated by a sum of sinusoids, each at a different frequency and amplitude. The more sinusoids included in the sum, the better the approximation. Statistics
