Oscilloscope

Osciloscopes are used not only in the audio (music) industry, but also science laboratories, hospitals and clinics.

Three crossed turning forks are in Yamaha brand logo.

Drum sounds can't be compononents of a chord. Chords can only consist of certain notes.

In 1897 german physicist K.F.Braun engineered the first oscilloscope.

Chords contain tierces (thirds).

Chord consists of minimum three diffrent notes.

Tuning fork is a tool used to pitch musical instruments.

Use of spectrum analyzer provides a plot and trace of signal amplitude in the frequency domain.

Nowadays there are many kinds of spectrum analyzers: stationary, portable, handhled and networked.

Tuning fork was invented by lute musician.

Key attributes of networked spectrum analyzers include the ability of synchronize data captures and effortless free acces.

Following the discovery of fast Fourier transform, in 1962 the first spectrum analyzer was engineered.

There are two type of chords- consonant chords and disonant chords.

Highest note define the position of chord.

Oscilloscopes are used to observe the change of electrical signal over time.

There are two types of spectrum analyzers: swept-tuned and time-sequence.
