  3. What You Can Do in FFT Analysis

The FFT enables you to learn about the frequency responses (level and phase) from the wave data. The FFT Analysis program, “FFT Analyzer”, reads the obtained wave data, performs FFT calculations, and displays various analyzed results onto graphs. The FFT is not only very useful for frequency analysis of level characteristics but also for observing the changes of phase and frequency components over the elapsed time.

The FFT is short for Fast Fourier Transform. As its name implies, it is a technique that analyzes the wave components at high speed, and decomposes wave data into various frequency components, allowing you to observe the changes over the elapsed time.
