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 ...

In an audio system, the accuracy of sound reproduction. A totally flat response means that there is no increase or decrease in volume level across the frequency range. Measured in decibels (dB), this ...

Frequency stability is key to the performance of nanoresonators. This stability is thought to reach a limit with the resonator's ability to resolve thermally induced vibrations. Although measurements ...

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 ...

The response is nearly 90 degrees out of phase with the excitation and the amplitude of response is large.

Switching power supplies rely on feedback control loops to ensure that the required voltage and current are maintained under varying load conditions. Design of the feedback control loop influences ...

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 ...
