Definition of frf acoustic analysis
WebThe great advantage of frequency response analysis lies in its frequency selective nature. Just one component of the frequency spectrum is extracted, and the corresponding system response at that frequency can be measured with great precision. This has significant advantages where the system under consideration has resonant features. WebA body is said to vibrate when it describes an oscillating motion about a reference position. The number of times a complete motion cycle takes place during the period of a second is called the frequency and is measured in hertz (Hz). The motion can consist of a single component occurring at a single frequency, as with a tuning fork, or of ...
