Dynamic Signal Analysis Basics

DSA is often referred to Dynamic Signal Analysis or Dynamic Signal Analyzer depending on the context. DSA uses various technologies for digital signal processing. Among them, the most fundamental and popular technology is based on the so-called Fast Fourier Transform (FFT). The FFT transforms the time domain signals into the frequency domain. To perform FFT-based measurements, it is important to understand the fundamental issues and computations involved.
