WebJul 20, 2024 · Now examine the gain, G, of the open loop system at this specific frequency. Three possibilities exist: G = 1; G < 1; or G > 1. Consider the G = 1 case; this gives an output sine wave of exactly the same amplitude as the input, but -180 degree phase shifted. In other words, it's upside down compared to the input.

WebSome of the key features of the system described in the Bode plot are: 1) Corner frequency F c, often called the −3 dB point. At this frequency the value of system gain or sensitivity is only 1 / 2 (0.707) of its value at DC (zero frequency). 2) Attenuation rate. Beyond the corner frequency the sensitivity of a first-order system rolls off at ... WebA: Bode plots are a actually a set of graphs which show the frequency response of a system.
