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. WebJan 4, 2024 · Bode plots allow easy determination of frequency values, compared with Nyquist plots where frequency values are not plotted. Generally, the lower-leftmost points on a Nyquist plot correspond to the highest frequencies, and following the trace to the right moves from high to low frequency.
