Tone generator

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

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

Since 1939 binding sound for pitching musical instruments is in 440Hz frequency. Formerly it was 432Hz.

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

Chords contain tierces (thirds).

Laryngologists use tuning forks in 432Hz becouse that's the frequency human body transcribes the best.

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

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

Highest note define the position of chord.

Tuning fork was invented by lute musician.

The first of real time computer games was made for oscilloscope. "Tennis for two" was programmed by William Higinbotham in 1958....

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

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

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

Chord consists of minimum three diffrent notes.

Three crossed turning forks are in Yamaha brand logo.
