Figure 10: Amplitude diagram of a 10th-order electronic filter plotted using a Bode plotter. The Bode plotter is an electronic instrument resembling an oscilloscope, which produces a Bode diagram, or a graph, of a circuit's voltage gain or phase shift plotted against frequency in a feedback control system or a filter. An example of this is ...

Vibration, standing waves in a string. The fundamental and the first 5 overtones in the harmonic series. A vibration in a string is a wave. Resonance causes a vibrating string to produce a sound with constant frequency, i.e. constant pitch. If the length or tension of the string is correctly adjusted, the sound produced is a musical tone.
For instance, in a vibrating guitar string, the ends of the string are nodes. By changing the position of the end node through frets, the guitarist changes the effective length of the vibrating string and thereby the note played. The opposite of a node is an anti-node, a point where the amplitude of the standing wave is at maximum. These occur ...
String gauge refers to the thickness and diameter of a guitar string, which influences the overall sound and pitch of the guitar depending on the guitar string used. [17] Some alternative tunings are difficult or even impossible to achieve with conventional guitars due to the sets of guitar strings, which have gauges optimized for standard tuning.
All strings are numbered, so for example the string closest to the player of a twelve-string guitar is always string twelve, and never "string six secondary" or similar constructions. In the context of instruments that possess at least one multi-string course , a single string normally played on its own may also be called a course .
New standard tuning (NST) is an alternative tuning for the guitar that approximates all-fifths tuning.The guitar's strings are assigned the notes C2-G2-D3-A3-E4-G4 (from lowest to highest); the five lowest open strings are each tuned to an interval of a perfect fifth {(C,G),(G,D),(D,A),(A,E)}; the two highest strings are a minor third apart (E,G).
The Pink Floyd song "Hey You" from the album The Wall and the Kansas song "Dust in the Wind" [2] from their Point of Know Return album use this form of guitar tuning. In "Hey You", David Gilmour replaced the low E string with a second high E (not a 12-string set, low E's octave string) such that it was two octaves up.
