A dynamic signal is usually captured as a transient signal of voltage, current, vibration, structural stresses, or a drop shock pulse.Dynamic signal analysis can be done in either time or frequency domain. In the time domain, you can observe the transient signal behavior, such as its signature variations, magnitude, and repetitiveness. You can also observe the signal’s behavior in the frequency domain, such as magnitude frequency response, harmonics, mechanical vibration signatures, and more.
