A signal generator is one of a class of electronic devices that generates electrical signals with set properties of amplitude, frequency, and wave shape. These generated signals are used as a stimulus for electronic measurements, typically used in designing, testing, troubleshooting, and repairing electronic or electroacoustic devices, though it often has artistic uses as well.
In his 1979 book Gödel, Escher, Bach: An Eternal Golden Braid, Douglas Hofstadter explained how Shepard scales could be used on the Canon a 2, per tonos in Bach's Musical Offering (called the Endlessly Rising Canon by Hofstadter [13]: 10 ) for making the modulation end in the same pitch instead of an octave higher. [13]: 717–719
The envelope generator became a standard feature of synthesizers. [ 1 ] Following discussions with the engineer and composer Vladimir Ussachevsky , the head of the Columbia-Princeton Electronic Music Center , in 1965, Moog developed a new envelope module whose functions were described in f T1 (attack time), T2 (initial decay time), ESUS ...

Alternatively, we can represent just intonation pitch classes by reducing to the octave, 1 ≤ p / q < 2. It is also very common to label pitch classes with reference to some scale. For example, one can label the pitch classes of n-tone equal temperament using the integers 0 to n − 1. In much the same way, one could label the pitch ...

As the two tones gradually approach unison, the beating slows down and may become so slow as to be imperceptible. As the two tones get further apart, their beat frequency starts to approach the range of human pitch perception, [1] the beating starts to sound like a note, and a combination tone is produced.
