What are FFT lines?
The fast Fourier transform (FFT) is a computational algorithm that efficiently implements a mathematical operation called the discrete-time Fourier transform. It transforms time-domain data into the frequency domain by taking apart a signal into sine and cosine waves.
What do FFT values mean?
The "Fast Fourier Transform" (FFT) is an important measurement method in the science of audio and acoustics measurement. It converts a signal into individual spectral components and thereby provides frequency information about the signal.
What does FFT plot show?
Frequency-domain graphs– also called spectrum plots and Fast Fourier transform graphs (FFT graphs for short)- show which frequencies are present in a vibration during a certain period of time.
What does the Fourier transform represent?
Fourier Transform is a mathematical model which helps to transform the signals between two different domains, such as transforming signal from frequency domain to time domain or vice versa. Fourier transform has many applications in Engineering and Physics, such as signal processing, RADAR, and so on.
