Frequency domain analysis is a method used to study signals and systems by transforming them from the time domain to the frequency domain, using mathematical tools like the Fourier Transform. This approach simplifies the analysis of systems, particularly in understanding how different frequency components of a signal are affected by the system, making it invaluable in fields like signal processing and control systems.
