Frequency response analysis

Frequency response analysis examines how a system or device reacts to different input signals varying in frequency. Essentially, it measures how well the system can reproduce or respond to signals at various speeds, identifying which frequencies are amplified, attenuated, or unaffected. This analysis helps engineers understand the system's behavior, stability, and performance—crucial for designing audio equipment, control systems, or structures to ensure they function correctly across a range of operating conditions. In short, it provides a comprehensive picture of how a system responds to different types of signals over the frequency spectrum.
