Frequency Response Graph Illustration

This illustration depicts a typical frequency response graph, showing how a system's output changes with varying input frequencies. It features a prominent red line that likely represents the primary frequency characteristic, exhibiting a flat passband, a sharp rolloff or attenuation region, and a further steady decline. A blue line might indicate an alternative or stepped response, while a vertical green line likely marks a specific cutoff or critical frequency point. The light blue lines near the red line's corner could signify tangent lines or points of interest like a knee frequency, demonstrating the system's gain or attenuation across the frequency spectrum. This type of graph is fundamental in electronics and signal processing for analyzing filter performance.
