Various kinds of applications and electronic tools for research purposes or the other many uses basic principles of spectrum analysis. Basically, spectrum analysis is a formula to convert signal with time domain into the frequency domain. The aim is to determine the fundamental frequency of a previously unknown signal. In the science of acoustics of this formula in the form of mathematical equations with the function of sigma operations or commonly known as FFT (Fast Fourier Transform). About the form of a mathematical formula or equation please be look here.
This time, author wants to share knowledge to you about the application of this system in a variety of these purposes. The application spectrum analysis contained mostly in a variety of audio software, especially those used for editing purposes. Most of this software is used by scientists to analyze a specific signal for known how its fundamental frequency. Not only scientists, the musicians were actually using this system, but they are not aware of and most of them do not know.
Ok, now we see an example, namely the digital guitar tuner tool. With a plucked string tone only we could know, even we do not need to hear with the ear sensitivity and feeling high. Basically, it works with spectrum analysis in dalamya. The input signal from a guitar that is received by the tool in the form of signals with time domain, with a digital sensor that uses a formula spectrum analysis then can be found frequency signals. By entering some data frequency tones in each octave on the control system contained in the instrument, it is automatically on the screen will appear if the tone being plucked or played.
