Consider an undamped single degree-of-freedom system experiencing harmonic excitation whose equation of motion (EOM) is given by: Here omega n is known as the natural frequency of response. The ...

Consider the undamped single-degree-of-freedom system shown below that is excited by harmonic base motion x B (t) = b sinωt, where ω is the frequency of the base motion: Here kbsinωt plays the role of ...

Let’s start our expla nations of loudspeaker measurement graphs with the most basic graph of a speaker’s behavior: the frequency response. Sometimes this is referred to as the amplitude response as ...

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...

One way that Audioholics have presented on-axis and off-axis frequency responses in our loudspeaker reviews are through waterfall plots. Wikipedia defines a waterfall plot as: “a three-dimensional ...
